Limerence

Psyche Revived by Cupid's Kiss, by Antonio Canova, first version 1787–1793

Limerence is the mental state of being madly in love<ref name=":26" /><ref name="beam-limerence-fisher" /> or intensely infatuated<ref name="Hayes" /><ref name=":16">Template:Harvnb</ref> when reciprocation of the feeling is uncertain. This state is characterized by intrusive thoughts and idealization of the loved one (also called "crystallization"), typically with a desire for reciprocation to form a relationship. This is accompanied by feelings of ecstasy or despair, depending on whether one's feelings seem to be reciprocated or not.<ref>Template:Harvard citation no brackets: "Uncertainty about LO's true reaction is an essential aspect of your own limerence." (p. 57); "Limerence's most reliable attribute, the characteristic that more than any other differentiates it from other states of attraction and affection that are also described by the phrase 'being in love,' is the intrusiveness of the preoccupation with LO." (p. 42); "[...] if ever the word 'object' was appropriate it was here, because to the degree that your reaction to a person is limerent, you respond to your construction of LO's qualities." (p. 33); Limerence at 100 percent may be ecstasy or it may be despair, and it may change from positive to negative at any level of intensity." (p. 44); "The goal of limerence is [...] the ecstatic bliss of mutual reciprocation." (p. 120)</ref> Research on the biology of romantic love indicates that the early stage of intense romantic love (also called passionate love) resembles addiction, but academics do not currently agree on how love addictions are defined.<ref name="proximateandultimate">Template:Cite journal: "Despite [the] attempts to define and describe romantic love, no single term or definition has been universally adopted in the literature.

Love and Limerence has been called the seminal work on romantic love, with Tennov's survey results and the various personal accounts recounted in the book largely marking the start of data collection on the phenomenon.<ref name="proximateandultimate" /><ref>Template:Harvnb</ref>

Overview

Dorothy Tennov's research was intended to be a scientific attempt at understanding the nature of romantic love.<ref>Template:Harvnb</ref> She identified a suite of psychological properties associated with a state she called limerence—usually termed "being in love", but distinguishable from other types of attraction patterns which the phrase "in love" might also refer to.<ref>Template:Harvnb</ref><ref name="fisher1998">Template:Cite journal</ref><ref name="beam-limerence-fisher" /><ref>Template:Harvnb: 'The condition is commonly referred to as "being in love", "romantic love", or "passionate love." Those terms may also refer to states other than the state identified as "limerence."' (p. 276); 'Experientially, [limerence] is a state of being "in love."' (p. 311)</ref> Other authors have considered limerence to be an emotional and motivational state for focusing attention on a preferred mating partner<ref name="fisher2002">Template:Cite journal: "In humans, the attraction system (standardly called romantic love, obsessive love, passionate love, being in love, infatuation, or limerence) is also characterized by feelings of exhilaration, 'intrusive thinking' about the love object, and a craving for emotional union with this partner or potential partner. [...] [A] list of 13 psychophysiological properties often associated with this excitatory state was compiled (see Fisher, 1998; Hatfield & Sprecher, 1986; Harris, 1995; Tennov, 1979). [...] Then 72-item questionnaire was compiled, based on these common properties [...]. [...] So this questionnaire was subsequently administered (along with several others) to all participants prior to their participation in Phase II of this study which involved fMRI of the brains of individuals who reported that they had 'just fallen madly in love.'"</ref> or an attachment process.<ref name="hazanshaver">Template:Cite journal</ref><ref name="feeneynoller">Template:Cite journal</ref>

Joe Beam calls limerence the feeling of being "madly in love".<ref name=":13">Template:Cite news</ref><ref name="beam-limerence-fisher"/> Nicky Hayes describes it as "a kind of infatuated, all-absorbing passion", the type of love Dante felt towards Beatrice or that of Romeo and Juliet.<ref name="Hayes">Template:Citation</ref> An unfulfilled, intense longing defines the state, where the individual becomes "more or less obsessed by that person and spends much of their time fantasising about them". Hayes suggests it's "the unobtainable nature of the goal which makes the feeling so powerful", and occasional, intermittent reinforcement may be required to support the underlying feelings.<ref name="Hayes"/> Frank Tallis calls limerence "love that does not need liking—love that may even thrive in response to rejection or contempt" and notes the "striking similarities" with addiction.<ref>Template:Harvnb</ref><ref name="tallis-addict"/>

A central feature of limerence for Tennov was the fact that her participants really saw the personal flaws of the object of their affection, but simply overlooked them or found them attractive.<ref>Template:Harvnb</ref><ref name="Fisher 2016 21">Template:Harvnb</ref> Tennov calls this "crystallization", after a description by the French writer Stendhal. This "crystallized" object of passionate desire is what Tennov calls a "limerent object" or "LO", "because to the degree that your reaction to a person is limerent, you respond to your construction of LO's qualities".<ref>Template:Harvnb</ref>

Limerence has psychological properties akin to passionate love,<ref>Template:Harvnb</ref><ref name=":4">Template:Harvnb</ref><ref name="fisher2002" /> but in Tennov's conception, limerence begins before a relationship and before the person experiencing it knows for certain whether it's reciprocated.<ref name=":33">Template:Harvnb: "Limerence theory holds the following: (1) The underlying mechanism is universal. (2) The state of limerence comes into being automatically when barriers to receptivity are down and a likely person appears. As limerence takes hold, certain laws of operation apply. What happens thereafter depends on how strongly it seems that the hoped-for reciprocation will indeed occur. This is largely, though perhaps not entirely, a matter of LO's actions. Small doses of attention from LO increase the intensity of the limerence experience. (3) Reciprocation leads to euphoria, followed by a union that might be stable or unstable, and that might or might not endure."</ref><ref name="conceptions-of-limerence" /> Limerence is frequently unrequited and turns into a lovesickness that can be difficult to escape.<ref>Template:Harvnb</ref><ref name="Hayes"/><ref name=":31" /><ref name="money-lovesick" /> Tennov argues that some type of situational uncertainty is required for the mental preoccupation and feelings to intensify, for example: mixed messages, physical or social obstacles, or even an LO's unsuitability as a partner.<ref>Template:Harvnb</ref> Some people may also fear intimacy so they distance themselves and avoid real connection.<ref name=":17" />

Not everyone experiences limerence.<ref name=":15">Template:Harvnb</ref> Tennov estimated that 50% of women and 35% of men experience limerence based on answers to certain survey questions she administered.<ref>Template:Harvnb</ref> Another survey administered by neuroscientist and limerence blogger Tom Bellamy indicated that 64% had experienced it at least once, and 32% "found it so distressing that it was hard to enjoy life".<ref>Template:Harvnb</ref>

It can be difficult for people who haven't experienced limerence to understand it, and it's often derided and dismissed as some kind of pathology, or an invention of romantic fiction.<ref>Template:Harvnb</ref> According to Tennov, limerence is not a mental illness, although it can be "highly disruptive and extremely painful", called "irrational, silly, embarrassing, and abnormal" or sometimes "the greatest happiness" depending on who is asked.<ref>Template:Harvnb</ref>

Famous examples

Relation to other concepts

Love

Dorothy Tennov gives several reasons for inventing a term for the state denoted by limerence (usually termed "being in love").<ref>Template:Harvnb</ref> One principle reason is to resolve ambiguities with the word "love" being used both to refer to an act (which is chosen), as well as to a state (which is endured):<ref name="Tennov 1999 15"/>

Many writers on love have complained about semantic difficulties. The dictionary lists two dozen different meanings of the word "love". And how does one distinguish between love and affection, liking, fondness, caring, concern, infatuation, attraction, or desire? [...] Acknowledgment of a distinction between love as a verb, as an action taken by the individual, and love as a state is awkward. Never having fallen in love is not at all a matter of not loving, if loving is defined as caring. Furthermore, this state of "being in love" included feelings that do not properly fit with love defined as concern.

(The type of love that focuses on caring for others is called compassionate love or agape.)<ref name="4th-dim" />Template:Paragraph breakThe other principle reason given is that she encountered people who do not experience limerence. The first such person Tennov discovered was a long-time friend, Helen Payne, whose unfamiliarity with the state emerged during a conversation on an airplane flight together.<ref name=":15"/> Tennov writes that "describing the intricacies of romantic attachments" to Helen was "like trying to describe the color red to one blind from birth".<ref>Template:Harvnb</ref> A person not currently experiencing limerence is called "nonlimerent", but Tennov cautions that it seemed to her that there is no "nonlimerent personality" and that potentially anyone could experience limerence.<ref>Template:Harvnb</ref> Tennov says:<ref name="Tennov 1999 15"/>

I adopted the view that never being in this state was neither more nor less pathological than experiencing it. I wanted to be able to speak about this reliably identifiable condition without giving love's advocates the feeling something precious was being destroyed. Even more important, if using the term "love" denoted the presence of the state, there was the danger that absence of the state would receive negative connotations.

Tennov addresses the issue of whether limerence is love in other passages.<ref>Template:Harvnb</ref> In one passage she clearly says that limerence is love, at least in certain cases:<ref name="Tennov 1999 120">Template:Harvnb</ref>

In fully developed limerence, you feel additionally what is, in other contexts as well, called love—an extreme degree of feeling that you want LO to be safe, cared for, happy, and all those other positive and noble feelings [...]. That's probably why limerence is called love in all languages. [...] Surely limerence is love at its highest and most glorious peak.

However, Tennov switches in tone and continues on with a fairly negative story of the pain felt by a woman reminiscing over the time she wasted pining for a man she now feels nothing towards, something which occupied her in a time when her father was still alive and her children "were adorable babies who needed their mother's attention." Tennov says this is why we distinguish limerence (this "love") from other loves.<ref name="Tennov 1999 120"/> In another passage, Tennov says that while affection and fondness do not demand anything in return, the return of feelings desired in the limerent state means that "Other aspects of your life, including love, are sacrificed in behalf of the all-consuming need." and that "While limerence has been called love, it is not love."<ref name="Tennov 1999 71">Template:Harvnb</ref>

Romantic love

Tristan and Isolde (Death), by Rogelio de Egusquiza. In this myth, the two drink a love potion by mistake, when Iseult is due to be married to Tristan's uncle, a king. In one version of the story, Tristan dies of a broken heart after a signal sent by Iseult is miscommunicated to him as a rejection.<ref>Template:Cite book</ref> In another version, Tristan is mortally wounded but Iseult cannot save him and gives up her spirit. The story is said to be the quintissential courtly romance.<ref>Template:Harvard citation no brackets</ref>

Template:For Dorothy Tennov sometimes considers limerence to be synonymous with the term "romantic love".<ref name=":37">Template:Harvnb: "The phenomenon that provides the subject of much romantic poetry and fiction has been called an addiction, an indication of low self-esteem, irrational, neurotic, erotomanic, and delusional." (p. x); "Limerence has been called 'romantic love' as opposed to 'real love' because to a vocal and often very articulate segment of the population it is unreal. But even when limerence is not believed in, or believed in only secretly, it still makes a good tale." (p. 161); "Writers have been philosophizing, moralizing, and eulogizing on the subject of 'erotic,' 'passionate,' 'romantic' love (i.e. limerence) since Plato (and surely long before that). [...] Limerent persons, sufferers of an unallowable condition, find themselves speechless save for the ambiguity of 'poetic' expression." (p. 172)</ref><ref>Template:Harvnb: "It is featured in roughly 90% of all drama, song and biography."</ref><ref name="observer" /> This term has a complicated history with an evolving definition, but the romantic love literary tradition represents some of the origins of the limerence concept. Often, these are stories depicting tragic or unfulfilled love, or early depictions of limerence.<ref>Template:Harvnb</ref><ref name=":37" /><ref name="Hayes" /> Some examples of romantic love stories in this vein are Layla and Majnun, Tristan and Iseult, Dante and Beatrice (from La Vita Nuova), Romeo and Juliet and The Sorrows of Young Werther.<ref>Template:Harvnb</ref><ref name="Hayes"/> Anakin and Padmé from Star Wars are a modern depiction.<ref>Template:Cite web</ref><ref>Template:Cite book</ref><ref>Template:Cite book</ref>

In this sense, romantic love is idealized, unrealistic and irrational, the kind of love often found in a fairy-tale depicting a tragedy. This can be contrasted with rational, practical and pragmatic love, or the kind of love found in steady, long-term relationships.<ref>Template:Cite web</ref><ref>Template:Harvnb</ref><ref>Template:Harvnb</ref><ref>Template:Harvnb</ref><ref name="Hayes"/>

The literary genre of romantic love dates back to troubadour poetry from the Middle Ages (or earlier) and the doctrine of courtly love.<ref>Template:Harvnb</ref> Tennov credits the cleric Andreas Capellanus as describing the state of limerence "very accurately" in The Art of Courtly Love, a book of statutes for the "proper" conduct of lovers.<ref name=":29">Template:Harvnb</ref><ref>Template:Harvnb</ref> The work includes rules such as "A true lover is constantly and without intermission possessed by the thoughts of his beloved." and "The easy attainment of love makes it of little value; difficulty of attainment makes it prized."<ref name="Tallis 2004 96">Template:Harvnb</ref> The work is believed to have helped spread the cultural doctrine of romantic love throughout Europe.<ref name="Tallis 2004 96"/><ref name="Lee 1998 54–55">Template:Harvnb</ref> Because of the literary and cultural origins of the term, the romantic love phenomenon is sometimes held to be socially constructed (especially by critics, according to Tennov); however, Tennov argues that limerence has a biological basis and evolutionary purpose.<ref>Template:Harvnb</ref><ref>Template:Harvnb</ref>

Tennov sometimes considers limerence synonymous with "falling" in love,<ref>Template:Harvnb</ref><ref name=":38" /> a concept which also has origins in the romantic tradition and the idea that love is tragic—evoking a connotation of physically falling over. One influential work in the Middle Ages described lovers who frequently fainted or lost consciousness.<ref name=":38">Template:Harvnb</ref>

In the modern scientific literature, "romantic love" is also often used as a synonym for passionate love, also called "being in love", and also often associated with limerence.<ref name="proximateandultimate" /><ref name=":52">Template:Cite journal</ref> Passionate love is a more general concept which academics have never adopted a universal term for.<ref>Template:Harvard citation no brackets</ref><ref name="proximateandultimate" /> Helen Fisher has commented that she prefers the term "romantic love" because she thinks it has meaning in society.<ref name="madlyinlove">Template:Cite podcast: "I don't think there is any difference [between romantic love and limerence]. I used to know [Dorothy Tennov] and I guess she wanted to invent a new term, and that was fine. I don't mind that, but I actually like the term of romantic love. Her concept of limerence was a rather sad one. It had a sad component to it. Anyway, she created a new term. It's a perfectly fine term. I could have used it myself. I decided not to because I felt that the term romantic love had meaning in society and I didn't see the need for a new term. But I certainly liked her work. I certainly read her book. I certainly knew her. I admired her. And I didn't happen to adopt the term limerence, but if people want to use it, fine with me. [...] My memory of [limerence]—and this is—she wrote that book in 1979, so I—and then she died pretty recently—and she was sick, and even the day that I met her at a conference, she was with her son who she really needed for, I don't know, for emotional or physical support. From my reading of it, she sort of felt that limerence was a somewhat unhealthy experience, that it so overtook you and could lead to some disaster."</ref> "Romantic love" was originally used in reference to the courtly idea, then came to have other connotations.<ref>Template:Harvard citation no brackets</ref> Tennov criticized the scientific literature in her era for not making proper distinctions, calling the reactions "confused and contradictory".<ref>Template:Harvard citation no brackets</ref> John Alan Lee, who developed a concept similar to limerence (called "mania"), has also complained of the literature's tendency to insist on a "one true love" or reduce a complex typology to something more monolithic.<ref name=":6" /><ref>Template:Harvard citation no brackets</ref><ref>Template:Harvard citation no brackets</ref>

Passionate and companionate love

Limerence is often associated with "passionate love", with Elaine Hatfield considering them synonymous, and commenting in 2016 that they're "much the same".<ref name="Hatfield 1988 197"/><ref name="potentgrip">Template:Cite news</ref><ref name=":52" /> Many researchers have considered them synonymous.<ref name="diamond2003" /><ref name="fisher2002" /><ref name="proximateandultimate" /><ref name="acevedo2009" /> Passionate love is:<ref>Template:Harvnb</ref>

A state of intense longing for union with an other. Reciprocated love (union with the other) is associated with fulfillment and ecstasy. Unrequited love (separation) with emptiness; with anxiety, or despair. A state of profound physiological arousal.

Passionate love is linked to passion, as in intense emotion: for example, joy and fulfillment, but also anguish and agony.<ref name="Hatfield 1985 58">Template:Harvnb</ref> According to Hatfield, passion is associated with a "hodgepodge of conflicting emotions", and the original meaning "was agony—as in Christ's passion."<ref>Template:Harvard citation no brackets</ref><ref name="Hatfield 1985 58" /> Passionate love is contrasted with companionate love: "the affection we feel for those with whom our lives are deeply entwined".<ref>Template:Harvnb</ref> Companionate love is said to be less intense, and often follows after passionate love in a relationship.<ref name="proximateandultimate" /><ref name="potentgrip" /><ref name="fisher2002" />

In Love and Limerence, Dorothy Tennov also lists passionate love among her synonyms for limerence, and refers to one of Hatfield's earlier writings on the concept.<ref>Template:Harvnb</ref> Tennov's study, however, focused on the aspects of love which cause distress, and also on individuals over relationships.<ref>Template:Harvnb</ref><ref name=":32">Template:Harvnb</ref> Another problem she encountered in her research was that informants would use terms like "passionate love", "romantic love" and "being in love" to refer to mental states other than what she refers to as limerence.<ref>Template:Harvnb</ref> Informants would use the word "obsession", yet not report the intrusive thoughts necessary to limerence, only that "thoughts of the person are frequent and pleasurable".<ref>Template:Harvnb</ref>

Passionate love is commonly measured with the Passionate Love Scale (PLS), originally designed to measure the state denoted by limerence.<ref name=":52" /><ref name=":25">Template:Cite journal</ref><ref>Template:Harvnb</ref> Later research found that the PLS has overly broad questions, and it actually has two general components (called factors): an obsession factor and a non-obsession factor.<ref name="ias">Template:Cite journal</ref><ref name="acevedo2009" /> The PLS obsession factor has items like "Sometimes I feel I can't control my thoughts; they are obsessively on my partner." and "An existence without my partner would be dark and dismal."<ref name="acevedo2009" /><ref name=":42">Template:Cite journal</ref> Limerence is comparable to passionate love with obsession:<ref name="acevedo2009" />

Passionate love, "a state of intense longing for union with another" [...], also referred to as [...] "limerence" (Tennov, 1979), includes an obsessive element, characterized by intrusive thinking, uncertainty, and mood swings.

The PLS non-obsession factor has items like "For me, my partner is the perfect romantic partner." and "I want my partner—physically, emotionally, and mentally."<ref name="acevedo2009" /> These love feelings (without obsession) can sustain over a longer period, according to newer research.<ref name="nbc2009">Template:Cite web</ref><ref name="time-marriage" /><ref name="acevedo2009" />

Infatuation

"Infatuation" has been considered synonymous with concepts like passionate love, "being in love" and limerence,<ref name="diamond2003" /><ref name="fisher2002" /><ref name="acevedo2009" /> but limerence is supposed to be more intense than a simple infatuation.<ref name="beam-limerence-fisher" /> Dorothy Tennov has stated that she did not use the word "infatuation" because while there is overlap, the word evokes different connotations.<ref name=":32" /> In one type of distinction, people use "infatuation" to express disapproval or to refer to unsatisfactory relationships, and "love" to refer to satisfactory ones.<ref>Template:Harvnb</ref> In Love and Limerence, Tennov considers "infatuation" to be pejorative, for example, being used to label teenage fantasizing about a celebrity which is actually limerence.<ref>Template:Harvnb</ref>

In the triangular theory of love, by Robert Sternberg, "infatuation" refers to romantic passion without intimacy (or closeness) and without commitment.<ref name=":0">Template:Cite journal</ref><ref name="Tallis 2004 45">Template:Harvnb</ref> Sternberg has stated that infatuation in his theory is essentially the same as limerence.<ref name=":0" />

Independent emotion systems

Helen Fisher's popular theory of independent emotion systems posits that there are three primary systems involved with human reproduction, mating and parenting: lust (the sex drive, or sexual desire), attraction (passionate love, infatuation or limerence) and attachment (companionate love). These three systems regularly work in concert together but serve different purposes and can also work independently.<ref name="fisher1998" /><ref name="fisher2002" /><ref name="co-opted">Template:Cite journal</ref> According to Fisher, lust, attraction and attachment can occur in any order.<ref>Template:Harvnb</ref><ref>Template:Cite web</ref> Independent emotions theory has been critiqued as being oversimplified, but the general idea of separate systems remains useful.<ref name="co-opted" />

When limerence is a component in an affair, for example, Fisher's theory can be used to help explain this.<ref name="fisher2002" /><ref>Template:Harvnb</ref> Fisher's theory is that a person can feel deep attachment for a long-term spouse, while they're in limerence with somebody else, while they can be sexually attracted to still yet other people.<ref name="fisher2002" /><ref>Template:Cite news</ref> Joe Beam comments that if somebody in a committed relationship ends up in limerence like this, it will pull them out of their relationship.<ref name=":13" />

Fisher's theory has also been used to explain "platonic" limerence (without sexual desire), because romantic love and sexual desire are functionally distinct.<ref name="diamond2003" /><ref>Template:Cite journal: "[M]ost researchers acknowledge a distinction between the earlier 'passionate' stage of love, sometimes called 'limerence' (Tennov, 1979), and the later-developing 'companionate' stage of love [...]. Although it may be easy to imagine sexual desire without romantic love, the notion of 'pure,' 'platonic,' or 'nonsexual' romantic love is somewhat more controversial. Yet empirical evidence indicates that sexual desire is not a prerequisite for romantic love, even in its earliest, passionate stages. Many men and women report having experienced romantic passion in the absence of sexual desire (Tennov, 1979) [...]."</ref> Tennov encountered this occasionally in her own research, finding cases of otherwise heterosexual women experiencing limerence for an older woman (compared to "hero worship"), but dismissed it as being outside her theory.<ref>Template:Harvard citation no brackets</ref> Lisa Diamond argues this is possible (even in contradiction to sexual orientation) because the brain systems evolved by repurposing the systems for mother-infant bonding (a process called exaptation). According to this theory, it would not have been adaptive for a parent to only be able to bond with an opposite sex child, so the systems must have evolved independent of sexual orientation. People most often fall in love because of sexual desire, but Diamond suggests time spent together and physical touch can serve as a substitute.<ref name="diamond2003" />

Attachment theory

John Bowlby's concept of "attachment" refers to a system evolved to keep infants in proximity of their caregiver (or "attachment figure").<ref name="diamond2003" /><ref name="hazanshaver" /><ref name="4th-dim">Template:Cite journal</ref> An attachment figure is a "secure base" for safety while exploring the environment, the child seeks proximity with the attachment figure when threatened, and suffers distress when separated.<ref name="4th-dim" /><ref name="hazanshaver" /> A prominent theory suggests this system is reused for adult pair bonds, as an exaptation or co-option, whereby a given trait takes on a new purpose.<ref name="hazanshaver" /><ref name="co-opted" /><ref name="diamond2003" /> "Attachment style" refers to differences in attachment-related thoughts and behaviors, especially relating to the concept of security vs. insecurity.<ref name="fraley-shaver-style">Template:Harvnb</ref><ref name="hazanshaver" /> This can be split into components of anxiety (worrying the partner is available, attentive and responsive) and avoidance (preference not to rely on others or open up emotionally).<ref name="fraley-shaver-style"/>

In Helen Fisher's theory, limerence and attachment are considered different systems with different purposes.<ref name="fisher1998" /><ref name="fisher2002" /> In the past, other authors have also suggested that limerence could be related to the anxious attachment style.<ref name="hazanshaver" /><ref name="feeneynoller" /> In their original 1987 paper conceptualizing romantic love as an attachment process (and relating limerence to attachment style), Cindy Hazan and Phillip Shaver caution that they aren't implying that the early phase of romance is equivalent to being attached.<ref name="hazanshaver" /> Other prominent authors have also criticized the idea that attachment theory can replace concepts like love styles or types of love.<ref>Template:Harvnb</ref><ref name="4th-dim"/> Limerence is considered a unique state which is distinct from attachment style, although people who have an anxious attachment style are more likely to have experienced it according to one survey.<ref name=":36">Template:Harvard citation no brackets</ref>

A 1990 study found considerable overlap of distributions between all three attachment styles and limerence (reported at similar frequencies), but the 15% of participants with an anxious attachment style scored about 10–20% higher on obsessive preoccupation and emotional dependence, and avoidants idealized more.<ref name="feeneynoller" /><ref>Template:Harvard citation no brackets</ref> Along with scoring highly on limerence, the anxious group also scored highly on the agape love attitude, for selfless, all-giving love.<ref name="feeneynoller" />

Love styles

The concept of a "love style" was invented by the sociologist John Alan Lee, to distinguish between different ways to love, or different types of love stories.<ref name=":20">Template:Cite journal</ref><ref>Template:Harvnb</ref> Limerence is considered similar or related to the love style mania (or manic love), named after the Ancient Greek theia mania (the madness from the gods).<ref name=":6">Template:Harvnb</ref><ref name="feeneynoller" /><ref name=":2">Template:Cite book</ref><ref>Template:Harvnb</ref> Lee developed his mania concept from sources similar to Tennov, like Andreas Capellanus and courtly love.<ref>Template:Harvnb</ref><ref>Template:Harvnb</ref><ref name="Lee 1998 54–55"/> Both Lee and Tennov also refer to "love madness", and Peele & Brodsky's Love and Addiction.<ref>Template:Harvard citation no brackets</ref><ref name=":26" /><ref>Template:Harvard citation no brackets</ref><ref name="Tennov 1999 x" />

A manic lover is obsessively preoccupied with the beloved.<ref name="Lee 1988 45">Template:Harvnb</ref> When asked to recall their childhood, a typical manic lover recalls it as unhappy, and they're usually lonely, dissatisfied adults.<ref>Template:Harvnb</ref> They're anxious to fall in love, but they're unsure of which physical type they prefer.<ref name=":20" /> Because they're unsure of who to fall in love with, they often fall in love with somebody quite inappropriate (a stranger, or even somebody they initially dislike) and project onto them the qualities they want but don't actually have.<ref>Template:Harvnb</ref><ref name="Lee 1988 46">Template:Harvnb</ref> According to Lee, "Mania can become almost an addiction nearly impossible for the addict to end on his own initiative."<ref>Template:Harvnb</ref> Mania is often the first love style of a young person, but others may not experience it until middle age—for example, after a marriage has lost interest.<ref name="Lee 1988 46"/> According to Lee, a cycle of manic loves is often caused by a desperate need to be in love, the cause of which the manic lover must locate and remedy to break free.<ref>Template:Harvnb</ref>

Lee describes the manic lover as jealous,<ref name="Lee 1988 45"/> but Tennov believes that a person can be limerent and not be jealous.<ref>Template:Harvnb</ref>

Among the other love styles, mania can be closely compared to eros (erotic love, or love of beauty).<ref name=":35" /><ref>Template:Harvard citation no brackets</ref> Both are often considered "romantic love", both involve "falling in love", and taken together eros & mania correspond to the way the Passionate Love Scale is defined.<ref name=":35">Template:Harvnb</ref><ref>Template:Harvard citation no brackets</ref><ref name="acevedo2009" /> An erotic lover is also intensely preoccupied with their beloved, but the thoughts are optimistic, while a manic lover is insecure.<ref>Template:Harvnb</ref> Unlike a manic lover, however, the erotic lover is aware of a physical type they consider ideal.<ref>Template:Harvnb</ref> As such, eros begins with a powerful initial attraction, referred to by Stendhal as "a sudden sensation of recognition and hope".<ref>Template:Harvnb</ref> Because the erotic lover is in search of an ideal then, the eros love style is not "blind".<ref>Template:Harvnb</ref> According to Lee, only manic lovers typically "crystallize" (as Stendhal described it) and ignore shortcomings and flaws in their beloved.<ref>Template:Harvnb</ref> The erotic lover also recalls their childhood as happy, and eros has been associated with secure attachment, while mania has been associated with attachment anxiety and neuroticism.<ref>Template:Harvnb</ref><ref>Template:Cite journal</ref><ref>Template:Harvnb</ref> A third love style, manic eros, is a mixture of the two, "moving either toward a more stable eros or toward full-blown mania". Some are typical erotic lovers under a temporary strain (moving toward mania), while others are typical manic lovers with a self-confident and helping partner (moving toward eros).<ref>Template:Harvnb</ref>

According to Lee, the love style ludus (noncommittal love as a game, avoidance and juggling multiple partners, e.g. Don Juan) and mania possess a "fatal attraction" for one another. It's surprisingly common, but not a good match for happy, mutual love.<ref>Template:Harvnb</ref> According to Tennov, Don Juan was probably nonlimerent, "more interested in exploiting the feeling in others for his own sexual gratification", although nonlimerence doesn't necessitate this.<ref name="NYT 1977" /><ref>Template:Harvard citation no brackets</ref>

Love addiction

Love addiction has had an amorphous definition over the years and does not yet denote a psychiatric condition.<ref name=":14">Template:Cite journal</ref> Limerence has been compared to and contrasted with the concept, and compared to addiction.<ref name="mccracken" /><ref name=":12" /><ref name=":18" /> Academics do not currently agree on when love is an addiction or when it needs to be treated. In a narrow view, love could be considered addiction only when it involves abnormal processes carrying negative consequences; alternatively, a broader view is that all love might be addiction, or simply an appetite, similar to how humans are dependent on food.<ref name=":3">Template:Cite journal</ref> Some authors include rejected lovers as love addicts,<ref>Template:Citation</ref> or argue that all passionate love is addiction, with limerence among their synonyms for this.<ref name="fisher2016" /><ref name="fisher2002" />

Erotomania

Limerence is sometimes compared to erotomania;<ref name="thelovedrug">Template:Cite news</ref><ref>Template:Harvnb</ref><ref>Template:Harvnb: "Lovesickness may take the form of a bizarre and obsessional fixation known in the clinical sexological literature as Clérambault-Kandinsky syndrome (CKS) [...], and also known as erotomania [...]. The CKS person is falsely convinced, to the point of delusion, that the target of his/her one-sided limerence is actually limerent in return, but dares not reveal it until a later date, even years ahead."</ref> however, erotomania is a delusional disorder where the sufferer falsely believes their love is reciprocated when it isn't.<ref name="fisher2016">Template:Cite journal</ref><ref name="tallis-erotomania">Template:Harvnb</ref> A person with erotomania might interpret irrelevant details (such as a love object wearing a particular accessory) as coded declarations of love, and invent ways to interpret outright rejections as unserious.<ref>Template:Harvnb</ref> Helen Fisher and colleagues have stated that erotomania may actually be a type of schizophrenia, and may not involve the same reward system activity in the brain as romantic love.<ref name="fisher2016" /> A person in limerence might "grasp for hope" and misinterpret signals, or imagine reciprocation in a fantasy, but they are receptive to receiving a clear rejection.<ref>Template:Harvnb</ref>

Evolutionary purpose

Limerence might have evolved as a handicap signal, similar to a peacock's tail, but signaling extreme commitment.<ref name=":232" />

Dorothy Tennov's speculation was that limerence has an evolutionary purpose.<ref>Template:Harvnb</ref><ref name="Tennov 1998 81–82">Template:Harvnb</ref>

For what ultimate cause might the state of limerence be a proximate cause? In other words, why were people who became limerent successful, maybe more successful than others, in passing their genes on to succeeding generations[.] Did limerence evolve to cement a relationship long enough to get the offspring up and running? [...] The most consistent result of limerence is mating, not merely sexual interaction but also commitment, the establishment of a shared domicile in the form of a cozy nest built for the enjoyment of ecstasy, for reproduction, and for the rearing of children.

According to the evolutionary theory by the anthropologist Helen Fisher, limerence is the activation of a motivation system for choosing and focusing energy on a potential mating partner. This brain system evolved for mammalian mate choice, also called "courtship attraction". In this phenomenon, a preferred mating partner is chosen based on a display of physical traits (such as a peacock's tail feathers) or other behaviors.<ref name="fisher1998" /><ref name="fisher2002" /><ref name=":8">Template:Cite journal</ref> Fisher also includes the attraction to personality traits and other characteristics in her mate choice theory for humans.<ref>Template:Harvnb</ref><ref>Template:Harvnb</ref><ref>Template:Cite magazine: "Passionate love, obsessive love, being in love, whatever you wish to call it. [...] In short, Explorers preferentially sought Explorers, Builders sought other Builders, and Directors and Negotiators were drawn to one another."</ref> Who a person falls in love with then is determined by their "love map", a largely unconscious list of traits they desire in an ideal partner. Love maps begin forming during childhood based on experiences with parents and friends, among other associations, but also change over time.<ref>Template:Harvnb</ref><ref>Template:Harvnb</ref> In most species, courtship attraction is brief, but intense romantic love can last much longer in humans.<ref name=":8" /> A competing evolutionary theory to Fisher's is that courtship attraction only encompasses something like love at first sight attraction, and the obsessive thoughts and intense attraction associated with early-stage romantic love instead evolved by co-opting (or re-using) the brain systems for mother-infant bonding. In this theory, romantic love may serve the function of mate choice but the brain systems were not originally for this.<ref name="proximateandultimate" /><ref name="co-opted" /><ref name="diamond2003" />

The neuroscientist Tom Bellamy believes that limerence evolved as a form of high-risk "extreme pair bonding" which can be explained as a handicap signal.<ref name=":232">Template:Harvnb</ref> The handicap principle in evolutionary theory is based on a contention between honest and fake signaling. When real emotions evolve, a niche is created for sham emotions (e.g. fake facial expressions) which are less risky to express. One explanation for why honest signals can evolve without becoming worthless (because of competing fakers) is that the honest signal can evolve if it's too expensive to fake. One example in nature is the peacock's tail, an example of conspicuous consumption, a cumbersome display which consumes nutrients. Only a healthy peacock can afford it, so in that case it may have evolved because it was a handicap, and used by females of the species as an indicator of health.<ref name=":152">Template:Harvnb; Pinker had the same theory as Bellamy, that intense romantic love is a handicap signal for commitment which should be attractive to a potential partner (pp. 417–419, 641).</ref> Limerence can be seen as a handicap signal meant to prove one's true commitment to their limerent object. Limerence might have evolved to leave the person experiencing it so insanely besotted that they would not leave for another mate, even a more valuable one.<ref name=":232" /> According to Helen Fisher's theory, monogamy emerged at a time when mothers needed extra food and protection (when bipedalism evolved, and then infant altriciality later), so romantic love evolved to last long enough while a mother cares for an infant.<ref>Template:Harvard citation no brackets; Fisher considers limerence and romantic love to be synonymous in her theory (pp. 19–20, 35).</ref><ref name="fisher2016" />

Tennov suggested that if the neural "machinery" for limerence is not a universal among all humans, then having both phenotypes (limerent and nonlimerent) in the population might be beneficial and an evolutionarily stable strategy.<ref>Template:Harvnb</ref> Limerents and nonlimerents tend not to always get along, nor have compatible relationship interests.<ref>Template:Harvard citation no brackets</ref> Limerence would also be affected by culture, according to Tennov. A culture which idealizes limerence might cause the nonlimerent LO to be more tolerant (or even imitate it), whereas a culture which is hostile to limerence might cause it to be denied, hidden or suppressed.<ref>Template:Harvard citation no brackets</ref>

Characteristics

Addiction

Key connections in the mesocorticolimbic pathway.

Limerence has been called an addiction.<ref name="Tennov 1999 x">Template:Harvnb</ref><ref name="mccracken" /><ref>Template:Cite web</ref> The early stage of romantic love is being compared to a behavioral addiction (i.e. addiction to a non-substance) but the "substance" involved is the loved person.<ref name="tallis-addict">Template:Harvnb: "[T]he limerent individual obsesses, idealises and shows high levels of emotional dependency. [...] There are certainly some striking similarities between love and addiction[,] particularly those described by Hite and Tennov. [...] At first, addiction is maintained by pleasure, but the intensity of this pleasure gradually diminishes and the addiction is then maintained by the avoidance of pain. [...] The 'addiction' is to a person, or an experience, not a chemical. [...] [O]ne of the characteristics shared by addicts and lovers is that they both obsess. The addict is always preoccupied by the next 'fix' or 'hit', while the lover is always preoccupied by the beloved. Such obsessions are associated with compulsive urges to seek out what is desired [...]."</ref><ref name="fisher2016" /><ref name=":7" /><ref>Template:Cite journal</ref> A team led by Helen Fisher used fMRI to find that people who had "just fallen madly in love" showed activation in an area of the brain called the ventral tegmental area (VTA) while looking at a photograph of their beloved.<ref name="fisher2002" /><ref name=":25" /><ref name="fisher2016" /> The VTA is an area in the midbrain which produces dopamine and projects to other reward system areas, like the nucleus accumbens and caudate nucleus which have also been active in brain scans of romantic love.<ref name=":25" /><ref name="fisher2016" /><ref name=":11" /><ref name=":9">Template:Cite journal</ref> Dopamine signaling in the VTA is the origin of a phenomenon called incentive salience, also called "wanting" (in quotes). This is the property by which cues in the environment stand out to a person and become attention-grabbing and attractive, like a "motivational magnet" which pulls a person towards a particular reward.<ref name=":10">Template:Cite journal</ref><ref name=":11">Template:Cite journal</ref><ref name=":9" /> People in love are thought to experience incentive salience in response to their beloved.<ref name="fisher2016" />

In addiction research, a distinction is drawn between "wanting" a reward (i.e. incentive salience, tied to mesocorticolimbic dopamine) and "liking" a reward (i.e. pleasure, tied to hedonic hotspots), aspects which are dissociable.<ref name=":10" /><ref name=":11" /> People can be addicted to drugs and compulsively seek them out, even when taking the drug no longer results in a high or the addiction is detrimental to one's life.<ref name="fisher2016" /> They can also "want" (i.e. feel compelled towards, in the sense of incentive salience) something which they do not cognitively wish for.<ref name=":10" /> In a similar way, people who are in love may "want" a loved person even when interactions with them are not pleasurable. For example, they may want to contact an ex-partner after a rejection, even when the experience will only be painful.<ref name="fisher2016" /> It is also possible for a person to be "in love" with somebody they do not like, or who treats them poorly.<ref name="Hatfield 1985 103–105">Template:Harvnb</ref> Fisher's team proposes that romantic love is a "positive addiction" (i.e. not harmful) when requited and a "negative addiction" when unrequited or inappropriate.<ref name="fisher2016" />

For a person in limerence that goes unrequited, the pleasurable aspects tend to diminish over time, with the person becoming lovesick and the addiction being maintained more by avoidance of the pain of separation.<ref name="tallis-addict"/><ref name=":31">Template:Harvard citation no brackets: "When that one person [LO] fails to reciprocate, the result may be long hours of sustained lovesickness that is relieved, and then only slightly, by achieving the limerence goal in imagination. There may come a time when the sufferer has had enough and wants to end the painful prepossession, when all bases for hope have been exhausted and it is time to abandon ship, only to find—and this is the madness of it—that these thoughts cannot be turned off and on at will as can most thoughts."</ref><ref name="ethnopharma"/><ref name="money-lovesick">Template:Harvnb: "Unrequited love is a synonym for unrequited limerence. It leaves a person vulnerable to an attack of lovesickness. Lovesickness may be transitory or prolonged, and major or minor in degree. It may be brought on by a person's anticipatory uncertainty about getting or not getting a reciprocal response to his/her limerence. Lovesickness may be brought on also by unequal proportions of limerence, for example, 100:70 instead of 100:100. The most unequal match is 100:0, total rejection.Template:PbThe formal definition of lovesickness (Money, 1986) is as follows.

lovesickness

the personal experience and manifest expression of agony when the partner with whom one has fallen in love is a total mismatch whose response is indifference, or a partial mismatch whose reciprocity is incomplete, deficient, anomalous, or otherwise unsatisfactory."</ref>

Lovesickness

The Love Potion, by Evelyn de Morgan. According to Tennov, "the love potion’s ingredients remain secret. Limerence is unaffected by the intensity of our desire to call it into or out of existence at our wills.",<ref>Template:Harvard citation no brackets</ref> but she asks "Is the love potion a hormone?"<ref>Template:Harvard citation no brackets</ref>

Usually limerence is unrequited, and a horrible experience for the limerent person, even debilitating for some.<ref name="thelovedrug" /><ref name="money-lovesick" /> Lovesickness is the resulting mental state, characterized by addictive cravings, frustration, depression, melancholy and intrusive thinking.<ref name=":31" /><ref name="ethnopharma" /><ref name="money-lovesick" /> In Dorothy Tennov's survey group, 42% reported being "severely depressed about a love affair" and 17% said they "often thought of committing suicide".<ref>Template:Harvnb</ref> Helen Fisher's fMRI scans of rejected lovers showed activation in brain areas associated with physical pain, craving and assessing one's gains and losses.<ref name="fisher2016" /> A limerent person can self-isolate, or be distracted, even to the detriment of school or job performance.<ref>Template:Harvnb</ref><ref name="money-lovesick" />

A shyness and confusion manifests out of fear of rejection when an LO is around—sometimes even in those normally confident, with the limerent person "terribly worried that [their] own actions may bring about disaster".<ref name="Tennov 1999 49" /> A 28-year-old truck driver says it's "like what you might call stage fright [...]. I was awkward as hell."<ref>Template:Harvnb</ref> The physiological effects of limerence include trembling, pallor, flushing, weakness, sweating, butterflies in the stomach and a pounding heart:<ref name="Tennov 1999 49">Template:Harvnb</ref><ref name="Fisher 2016 22">Template:Harvnb</ref> "When I asked interviewees in the throes of the limerent condition to tell where they felt the sensation of limerence, they pointed unerringly to the midpoint in their chest. So consistently did this occur that it would seem to be another indication that the state described is indeed limerence".<ref name="Tennov 1999 64">Template:Harvnb</ref>

In a 1987 survey by Shere Hite in which many participants described relationships which were clearly limerent, 69% of married women and 48% of single women "neither liked, nor trusted, being in love", and their responses indicated being in love was mostly distressing. 17% "could no longer take love seriously".<ref>Template:Harvnb</ref> Tennov describes being under the spell herself: "Before it happened, I couldn't have imagined it[.] Now, I wouldn't want to have it happen again."<ref name="wapo1990">Template:Cite news</ref> Some people even described to her incidents of self-harm, but Tennov maintains that such tragedies involve limerence "augmented and distorted" by other factors.<ref>Template:Harvnb</ref>

There's debate among academics over when love can be considered addiction, and whether addiction is really a "true" mental illness.<ref name=":3" /><ref name="tallis-addict" /> Lovesickness has been pathologized in previous centuries, but is not currently in the ICD-10, ICPC or DSM-5.<ref name="ethnopharma">Template:Cite journal: "The feeling of romantic love (also 'infatuated love' or 'limerence'; see Tennov, 1998) is the strongest sensation known to humankind and is characterized by a mix of unbearable exhilarating joy, anxiety, obsessive thinking and craving for emotional and physical union [...]. [...] Unrequited love, erotic frustration and the craving for the beloved object manifest themselves in what is commonly referred to as lovesickness (see Tennov, 1998). This often depressive and melancholic state of mind is characterized by intrusive thinking and also has an addictive component."</ref><ref name="autogenerated12">Template:Cite journal</ref> The lovers described by Tennov bear a particular resemblance to addicts, but limerence was not intended to denote an abnormal state.<ref name="tallis-addict" /> The author and clinical psychologist Frank Tallis has made the argument that all love—even normal love—is largely indistinguishable from mental illness.<ref>Template:Harvnb</ref>

Template:Quote box The symptoms of lovesickness still bear resemblance to entries in the DSM, which now includes some addictions, and there are other entries which also resemble core symptoms of falling in love: preoccupation, episodes of melancholy, rapture and instability of mood.<ref>Template:Harvnb</ref><ref name="autogenerated12" /> These correspond to conventional diagnoses of obsessionality (or OCD), depression, mania (or hypomania) and manic depression.<ref>Template:Harvnb</ref><ref name="autogenerated12" /> Other examples are physical symptoms resembling panic attacks (pounding heart, trembling, shortness of breath and lightheadedness), excessive worrying about the future resembling generalized anxiety disorder, appetite disturbance and sensitivity about one's appearance resembling anorexia nervosa, and the feeling that life has become a dream resembling derealization and depersonalization.<ref>Template:Harvnb</ref>

It has been argued that falling in love is involuntary, but whether one's subsequent behavior could be considered autonomous may depend on whether addictive love is viewed as a normal or abnormal state.<ref name=":3" /> Tallis argues that love evolved to override rationality so that one finds a lover to reproduce with, regardless of the personal costs of bearing and raising a child:<ref>Template:Harvnb</ref>

At first sight, it seems extraordinary that evolutionary forces might conspire to shape something that looks like a mental illness to ensure reproductive success. Yet, there are many reasons why love should have evolved to share with madness several features—the most notable of which is the loss of reason. Like the ancient humoral model of love sickness, evolutionary principles seem to have necessitated a blurring of the distinction between normal and abnormal states. Evolution expects us to love madly, lest we fail to love at all.

According to Tennov, "Love has been called a madness and an affliction at least since the time of the ancient Greeks and probably earlier than that."<ref>Template:Harvnb</ref> Historically, lovesickness has been attributed to arrows shot by Eros, a sickness entering through the eyes (like evil eye), excess of black bile, spells, potions and other magic. The first known treatise on the subject is Remedia Amoris, by the poet Ovid. People have tried to treat lovesickness with a variety of natural products, charms and rituals.<ref name="ethnopharma" /> The bioethicist Brian Earp and his colleagues have argued that the voluntary use of anti-love drugs (made to cause a person to fall out of love) could be ethical, but there's no drug now which is a realistic candidate.<ref>Template:Cite journal</ref><ref>Template:Cite journal</ref><ref name="refuting">Template:Cite journal</ref><ref name="ethnopharma" />

Intrusive thinking and fantasy

Intrusive thinking is a hallmark or cardinal trait of romantic love.<ref name="co-opted" /><ref name=":25" /><ref name="proximateandultimate" /><ref name="langeslag2012"/> Tennov wrote that "Limerence is first and foremost a condition of cognitive obsession."<ref>Template:Harvnb</ref> One study found that on average people in love spent 65% of their waking hours thinking of their beloved.<ref name="langeslag2012">Template:Cite journal</ref> Arthur Aron says "It is obsessive-compulsive when you're feeling it. It's the center of your life."<ref name="usatoday"/> At the height of obsessive fantasy, a person in limerence can spend 85 to nearly 100% of their days and nights doting in reverie, lose their ability to focus and become distracted.<ref name="Fisher 2016 21"/>

A limerent person can spend time fantasizing about future events even if they never come true, as the anticipation on its own yields dopamine.<ref name="mccracken" /> According to Tennov, limerent fantasy is unsatisfactory unless rooted in reality, because the fantasy must seem realistic enough to be somewhat possible.<ref>Template:Harvnb</ref> Fantasies can nevertheless be wildly unrealistic: one person recalled an elaborate rescue, in which he saves an LO's 5-year-old cousin from motorcycles, only to be killed by a snake in the lap of his LO as she tells him "I love you".<ref>Template:Harvnb</ref> This fantasizing along with the replaying of actual memories forms a bridge between ordinary life and the eventual hoped-for moment: consummation. Tennov says that limerent fantasy is "inescapable", something that just "happens" as opposed to something one "does".<ref>Template:Harvnb</ref>

Ellen Berscheid & Elaine Hatfield (cited by Tennov)<ref>Template:Harvard citation no brackets</ref> state on the importance of fantasy:<ref>Template:Harvard citation no brackets</ref>

When the lover closes his eyes and daydreams, he can summon up a flawless partner—a partner who instantaneously satisfies all his unspoken, conflicting, and fleeting desires. In fantasy he may receive unlimited reward or he may anticipate that he would receive unlimited reward were he ever to actually meet his ideal. Compared to our grandiose fantasies, the level of reward we receive in our real interactions is severely circumscribed. As a consequence, sometimes the most extreme passion is aroused by partners who exist only in imagination or partners who are barely known.

One theory of obsessive thinking draws a parallel with drug addiction: the early stage of romantic love is compared to addiction, and drug addicts also exhibit obsessive thoughts about drug use.<ref name=":7">Template:Cite journal</ref><ref name="tallis-addict"/> Tennov conceived of limerent fantasy (based in reality) as "intricate strategy planning".<ref name="Tennov 1999 247">Template:Harvnb</ref> In the late 1990s, it was also speculated that falling in love lowered serotonin levels in the brain, believed to cause intrusive thoughts.<ref name="fisher1998"/><ref name="marazziti">Template:Cite journal</ref> This was based on a comparison to obsessive–compulsive disorder, but the experiments were ambiguous.<ref name="leckmanmayes">Template:Cite journal</ref><ref name="marazziti" /><ref name="proximateandultimate"/> The experiments also measured blood levels rather than in the central nervous system, making the results difficult to interpret. The first experiment found that serotonin transporter levels were lower, but a second experiment found that blood serotonin levels in men and women were affected differently.<ref name="proximateandultimate"/><ref name="langeslag2012"/><ref name="marazziti" /> This second experiment found that obsessive thinking was actually associated with increased serotonin in women.<ref name="langeslag2012" /> SSRI use also seemed to not have an effect on obsessive thinking in a 2025 study.<ref name=":28" />

For some people who fear intimacy or have a history of trauma, limerent fantasy might be an escape, without the threat of real intimacy.<ref name=":18">Template:Cite news</ref><ref name=":17" />

Crystallization

Template:Multiple image Crystallization, for Tennov, is the "remarkable ability to emphasize what is truly admirable in LO and to avoid dwelling on the negative, even to respond with a compassion for the negative and render it, emotionally if not perceptually, into another positive attribute."<ref>Template:Harvnb</ref><ref name="fisher1998" /> The term comes from the French writer Stendhal's 1821 treatise on love, De l'Amour, in which he describes an analogy where a tree branch is tossed into a salt mine. After several months, the tree branch (or twig) becomes covered in salt crystals which transform it "into an object of shimmering beauty". In the same way, unattractive characteristics of an LO are given little to no attention, so that the LO is seen in the most favorable light.<ref>Template:Harvnb</ref> One of Tennov's informants says:<ref>Template:Harvnb</ref>

Yes I knew he gambled, I knew he sometimes drank too much, and I knew he didn't read a book from one year to the next. I knew and I didn't know.

This kind of "misperception" or "love is blind" cognitive bias<ref name="proximateandultimate" /><ref name="Fisher 2016 21"/> is more often referred to as "idealization",<ref name="Tennov 1999 31">Template:Harvnb</ref> which modern research considers to be a form of positive illusions.<ref name="proximateandultimate" /><ref name="murray1996">Template:Cite journal</ref> Past authors have sometimes depicted idealization as a malady, but significant scientific evidence has shown that positive illusions actually contribute to relationship satisfaction, long-term well-being and decreased risk for relationship discontinuation.<ref name="murray1996" /><ref name="song-positive">Template:Cite journal</ref><ref name="fisher-positive">Template:Harvard citation no brackets</ref> Tennov argues against the term "idealization", because she says it implies that the image seen by the person experiencing romantic passion "is molded to fit a preformed, externally derived, or emotionally needed conception".<ref name="Tennov 1999 31"/> In crystallization, the term she prefers, "the actual and existing features of LO merely undergo enhancement."<ref name="Tennov 1999 31"/>Template:Paragraph breakA limerent person may overlook red flags or incompatibilities.<ref name=":17">Template:Cite news</ref><ref name=":30" /> Crystallization can be an impediment to recovery, as one of Tennov's informants relates:<ref>Template:Harvnb</ref>

I decided to make a list in block letters of everything about Elsie that I found unpleasant or annoying. It was a very long list. On the other side of the paper, I listed her good points. It was a short list. But it didn't help at all. The good points seemed so much more important, and the bad things, well, in Elsie they weren't so bad, or they were things I felt I could help her with.

Readiness

Some people have a heightened susceptibility to limerence, a state Tennov calls "readiness", "longing for limerence" or being "in love with love".<ref>Template:Harvnb</ref><ref name=":21">Template:Cite journal</ref> This can occur due to biological factors (like adolescence), but also psychological factors (like loneliness or discontent). Sometimes readiness can be so intense that a person falls in love with somebody with only minimal appeal.<ref name=":21" /> The psychoanalysts Freud and Reik believed that unhappy people tend to be the most vulnerable to love and fantasy; Elaine Hatfield concurs, saying "the greater our need, the more grandiose our fantasies".<ref>Template:Harvard citation no brackets; Note: Hatfield has considered passionate love and limerence synonymous (Hatfield, 1988, p. 197).</ref>

Shaver & Hazan observed that lonely people are more susceptible to limerence,<ref>Template:Citation</ref> arguing that "if people have a large number of unmet social needs, and are not aware of this, then a sign that someone else might be interested is easily built up in that person's imagination into far more than the friendly social contact that it might have been. By dwelling on the memory of that social contact, the lonely person comes to magnify it into a deep emotional experience, which may be quite different from the reality of the event."<ref>Template:Harvnb</ref>

Uncertainty and hope

According to Dorothy Tennov, "uncertainty" is a key element to limerence:<ref name="Tennov 1999 56">Template:Harvnb</ref>

The recognition that some uncertainty must exist has been commented on and complained about by virtually everyone who has undertaken a serious study of the phenomenon of romantic love. Psychologists Ellen Bersheid and Elaine Walster discussed this common observation made, they note, by Socrates, Ovid, the Kama Sutra, and "Dear Abby," that the presentation of a hard-to-get as opposed to an immediately yielding exterior is a help in eliciting passion.

Rather than being an emotion itself, romantic love is a motivational state which can produce different emotions depending on the situation: positive feelings when things go well and negative feelings when things go awry.<ref name="refuting" /><ref name="fisher1998" /><ref name="fisher2002" /><ref name=":4" /> The "goal" according to Tennov's analysis is "oneness" with the LO, i.e. mutual reciprocation or return of feelings.<ref>Template:Harvard citation no brackets</ref>

According to Tennov's theory, two elements are required for limerence to develop and intensify: hope and uncertainty. There must be at least some hope that an LO will reciprocate, but uncertainty over their true feelings is required for the preoccupation and mood changes to intensify.<ref>Template:Harvnb</ref> In some cases, uncertain reciprocation can produce mood swings which are so abrupt as to cause emotional volatility, even in generally stable people. One of Tennov's informants recalls: "When I felt [Barry] loved me, I was intensely in love and deliriously happy; when he seemed rejecting, I was still intensely in love, only miserable beyond words."<ref name="Tennov 1999 44">Template:Harvnb</ref>

Limerence normally subsides when either:<ref name="conceptions-of-limerence" />

1. all hope of reciprocation is ended;
2. the limerent person enters a relationship with the LO and receives adequate reciprocation;
3. limerence is "transferred" to a different LO.

In even some further cases ("and this is the madness of it", Tennov says), the lovesickness and intrusive thoughts can still remain, even after all hope is exhausted and the sufferer wants to be rid of the state.<ref name=":31" /> After a transition to addiction, the executive brain is sidestepped, and some reactions and behavioral habits become essentially automatic.<ref>Template:Harvard citation no brackets</ref>

"Both gamblers and limerents find reason to hope in wild dreams." Template:Nowrap<ref>Template:Harvnb</ref>

The uncertainty of limerence has been interpreted as intermittent reinforcement by Robert Sternberg,<ref name=":5">Template:Cite journal</ref> keeping the brain "hooked" in.<ref name="mccracken" /> When people behave inconsistently or contrary to expectations, this can spark interest and be a fuel for passion (either ecstasy or agony).<ref>Template:Harvnb</ref> This relies on a mechanic of dopamine, which does not encode reward per se, but rather encodes a "reward prediction error" signal: whether a given reward is better, equal to, or worse than expected.<ref name=":62">Template:Harvard citation no brackets</ref><ref name="schultz2000">Template:Cite journal</ref><ref name="schultz2016">Template:Cite journal</ref> The type of situation involved resembles a slot machine, where the rewards are designed to be always unpredictable so the gambler cannot understand the pattern. Unable to habituate to the experience, for some people the exhilarating high from the unexpected wins leads to gambling addiction and compulsions. If the machine paid out on a regular interval (so that the rewards were expected), it would not be as exciting.<ref name=":62" /> The uncertainty of receiving an occasional message from an LO is "gasoline poured on the fire", according to Judson Brewer.<ref name="mccracken" />

Uncertainty can also be introduced by the presence of barriers to a relationship, like parental interference or a deceived spouse.<ref>Template:Harvnb</ref> This "intensification through adversity" was crucial to the mutual limerence of Romeo and Juliet, hence this is often called "the Romeo and Juliet effect".<ref name="Tennov 57">Template:Harvnb</ref> Helen Fisher called it "frustration attraction", and attributed it to dopamine neurons which prolong their firing in anticipation of an expected reward which is delayed.<ref name="Fisher 2016 21" /><ref>Template:Harvnb</ref> Fisher also believed that separation evokes panic and stress, which activates the hypothalamic–pituitary–adrenal axis. It's ironic, she says, because this can also produce dopamine, so "as the adored one slips away, the very chemicals that contribute to feelings of romance grow even more potent".<ref name="Fisher 2016 21–22">Template:Harvnb</ref><ref>Template:Harvnb</ref> According to Tennov, "It is limerence, not love, that increases when lovers are able to meet only infrequently or when there is anger between them."<ref name="Tennov 1999 71" />

One can attempt to extinguish limerence by removing any hope that an LO will reciprocate.<ref>Template:Harvnb</ref><ref name="conceptions-of-limerence">Template:Cite book</ref> An individual who is the object of unwanted limerent attraction should give the clearest possible rejection, rather than something ambiguous such as "I like you as a friend, but...".<ref>Template:Harvnb</ref>

Ecstatic union

"I felt as though the clouds were not on the horizon but under my feet. How sweet it was." Template:Nowrap<ref>Template:Harvnb</ref>

Although limerence is usually unrequited, it can lead to a relationship in some cases.<ref>Template:Harvard citation no brackets</ref><ref name="thelovedrug" /><ref name="Hayes" /><ref name="conceptions-of-limerence" /> According to Tennov's theory and observations, small doses of attention from an LO (along with uncertainty) increase the intensity of limerence, and a sensation of buoyancy or "walking on air" is felt when reciprocation seems near.<ref name=":33" /><ref>Template:Harvard citation no brackets</ref> "Reciprocation leads to euphoria, followed by a union that might be stable or unstable, and that might or might not endure."<ref name=":33" /> This "ecstatic union" (a phrase coined by Simone de Beauvoir) is recalled by one of Tennov's informants: "The landlord had given me notice and the bank loan had not gone through, and I could not bring myself to care! Whatever happened, it would be wonderful somehow. My delight in simply existing eclipsed everything else".<ref>Template:Harvard citation no brackets</ref> 95% of her survey group called love "a beautiful experience".<ref>Template:Harvard citation no brackets</ref>

A 2025 study of the largest cross-cultural survey of currently in-love people (who were also in relationships) categorized 29.42% of their sample as "intense" romantic lovers, and 28.57% of those fell in love before their relationship. (That is, only 8.4% of the study were both intensely in love and also fell in love before their relationship. The majority of intense lovers fell in love after their relationship started, with one month after being the average.)<ref>Template:Cite journal</ref>

Normally then, limerence diminishes inside a relationship, with reciprocity.<ref>Template:Harvard citation no brackets</ref><ref name="conceptions-of-limerence" /> Desire fades because of a habituation effect on dopamine activity: as a reward is more easily and predictably obtained, the dopamine release in response to reward cues decreases.<ref>Template:Harvard citation no brackets</ref> Research also suggests that oxytocin activity might inhibit the more excessive effects of addiction, with oxytocin from the attachment system being more active in reciprocated, well-functioning relationships compared to unrequited situations.<ref name=":7" /><ref>Template:Cite journal</ref><ref name="co-opted" /> In some cases, however, just getting into a relationship by itself may still not be enough for limerence to diminish, if reciprocation is insufficient.<ref name="conceptions-of-limerence" /><ref name=":34">Template:Harvard citation no brackets</ref> According to Tennov, reciprocation must be "sustained and believable", else limerence can continue inside a relationship if the partner (LO) behaves in a nonlimerent way.<ref name="conceptions-of-limerence" /> Limerence and uncertainty theory have also been interpreted in terms of attachment anxiety, worsening the symptoms.<ref name="what-fuels-passion">Template:Cite journal</ref><ref name=":36" /> This can be caused both by an anxious attachment style or a situation where (for example) an avoidant partner can make a normally secure person feel and act anxious (which is a problem in psychology, called a person–situation debate).<ref name="hazanshaver" /><ref>Template:Harvnb</ref> One man interviewed by Tennov described being caught in one-sided limerence with his wife "in constant fear of divorce" for 25 years; however, after their eventual breakup he found a different partner whom he did not have this reaction to.<ref name=":34" /><ref name=":21" />

The Passionate Love Scale obsession factor (compared to limerence) has been correlated with relationship satisfaction in short-term relationships; however, studies have also found that as romantic obsession continues inside a relationship over a longer time, the correlation is with decreased satisfaction. This is speculated to be due to low self-esteem and insecure or anxious attachment.<ref name="acevedo2009" /><ref name=":110" /> Other studies have found that anxious attachment mediated the relationship between neuroticism and its related love styles, and the mania love attitude (which has been related to limerence) mediated the relationship between neuroticism and relationship satisfaction.<ref>Template:Harvard citation no brackets</ref><ref name="feeneynoller" />

In some cases, limerence can be extinguished quite quickly after a relationship is established, because with more routine contact the participants begin to notice things they don't like about each other.<ref name="Hayes" /><ref name=":5" /> A reminiscent concept from triangular theory of love is "fatuous love" (passion, with commitment, without intimacy): as in new passionate lovers who commit to marry without really knowing each other. Usually this fatuous passion fades and turns into just an unhappy commitment by itself, called "empty love".<ref>Template:Harvnb</ref> The philosopher Bertrand Russell is quoted by Tennov in her discussion of uncertainty,<ref name="Tennov 1999 56" /> quipping that "when a man has no difficulty in obtaining a woman, his feeling towards her does not take the form of romantic love", but Russell goes on to say that "I think it is good—that romantic love should form the motive for a marriage, but it should be understood that the kind of love which will enable a marriage to remain happy and to fulfil its social purpose is not romantic but is something more intimate, affectionate, and realistic. In romantic love the beloved object is not seen accurately, but through a glamorous mist".<ref>Template:Cite book</ref>

According to Tennov, ideally limerence will be replaced by another type of love.<ref name="conceptions-of-limerence" /> In this way, feelings may evolve: "Those whose limerence was replaced by affectional bonding with the same partner might say, 'We were very much in love when we married; today we love each other very much.Template:'"<ref>Template:Harvnb</ref> The more stable type of love which is usually the characteristic of long-term relationships is commonly called companionate love, storge or attachment.<ref name="acevedo2009" /><ref name="4th-dim" /><ref name="fisher2002" /> An fMRI experiment of people who were in happy, long-term relationships (10 years or more) but professed to still be "madly" in love found brain activations in dopamine-rich reward areas (interpreted as "wanting" or "desire for union"), but also activity in the globus palludus, a site for opiate receptors identified as a hedonic hotspot ("liking"). Unlike people who were newly in love, these participants also did not show activity in areas associated with anxiety and fear, and reported far less obsessional features.<ref name="time-marriage">Template:Cite web</ref><ref name=":42" /><ref name="acevedo2009" />

Duration

"Limerence can live a long life sustained by crumbs." Template:Nowrap<ref>Template:Harvnb</ref>

Tennov estimates based on her questionnaire and interviews that limerence most frequently lasts between 18 months and 3 years, with an average of 2 years, but may be as short as mere days or as long as a lifetime.<ref>Template:Harvnb</ref> One woman wrote to Tennov about her mother's limerence which lasted 65 years.<ref name="wapo1990" /> Tennov calls it the worst case when the limerent person cannot get away, because the LO is a coworker or lives nearby.<ref name="wapo1990" /> Limerence can last indefinitely sometimes when unrequited, especially when reciprocation is uncertain: with intermittent reinforcement and mixed signals, for example, an LO ignoring the limerent person for awhile and then suddenly calling.<ref name="thelovedrug" /><ref name=":5" /><ref name="mccracken" /> Stringing a limerent person along with intermittent communication is called "breadcrumbing".<ref name="mccracken" /><ref>Template:Cite web</ref>

Tennov's estimate of 18 months to 3 years is sometimes used as the normal duration of romantic love.<ref name=":1">Template:Cite journal</ref><ref name="proximateandultimate" /> The other common estimate, 12–18 months, comes from Donatella Marazziti's experiment comparing serotonin transporter levels of people in love with OCD patients.<ref name="fisher2016" /><ref name="marazziti" /> In this experiment, subjects who had fallen in love within the past 6 months (who were in a relationship) were measured to have serotonin transporter levels which were different from controls, levels which returned to normal after 12–18 months.<ref name="marazziti" />

Love regulation

Love regulation, studied by the psychologist Sandra Langeslag, is "the use of behavioral or cognitive strategies to change the intensity of current feelings of romantic love".<ref name="regulating">Template:Cite journal</ref> Langeslag works with Helen Fisher's model (lust, attraction and attachment, i.e. independent emotion systems), but uses the terms infatuation (i.e. passionate love) and attachment (i.e. companionate love).<ref>Template:Cite web</ref><ref name="refuting" /> It's a common misconception that love feelings are uncontrollable, or even should not be controlled; however studies using EEG and psychometrics have shown that love regulation is possible and can be useful.<ref name="refuting" /><ref name="regulating" />

In a technique called cognitive reappraisal, one focuses on positive or negative aspects of their beloved, the relationship, or imagined future scenarios:

• In positive reappraisal, one focuses on positive qualities of the beloved ("he's kind", "she's spontaneous"), the relationship ("we have so much fun together") or imagined future scenarios ("we'll live happily ever after").<ref name="regulating" /><ref name="valentine" /> Positive reappraisal increases attachment and can increase relationship satisfaction.<ref name="valentine" />
• In negative reappraisal, one focuses on negative qualities of the beloved ("he's lazy", "she's always late"), the relationship ("we fight a lot") or imagined future scenarios ("he'll cheat on me").<ref name="regulating" /><ref name="valentine">Template:Cite news</ref> Negative reappraisal decreases feelings of infatuation and attachment, but decreases mood in the short term. Langeslag has recommended distraction as an antidote to the short-term decrease in mood.<ref name="valentine" /><ref name="times">Template:Cite news</ref>

Preliminary results from a 2024 study of online limerence communities conducted by Langeslag found that negative reappraisal decreased limerence for the study participants.<ref>Template:Cite AV media</ref> A therapist named Brandy Wyant has also had her limerent clients list reasons their LO is not perfect, or reasons they and their LO are not compatible.<ref name="mccracken" /> Love regulation doesn't switch feelings on or off immediately, so Langeslag recommends writing a list of things once a day as an example.<ref name="bestway2">Template:Cite magazine</ref>

Based on the addiction theory of romantic love, Helen Fisher and colleagues recommend that rejected lovers remove all reminders of their beloved, such as letters or photos, and avoid contact with the rejecting partner. Reminders can cause cravings which prolong recovery. They also suggest that positive contact with friends could reduce cravings. Rejected lovers should stay busy to distract themselves, and engage in self-expanding activities.<ref name="fisher2016" /> Setting a "no contact" rule during recovery can facilitate self-care and time to reflect on the situation.<ref>Template:Cite web</ref>

Controversy

Template:See also In 2008, Albert Wakin, a professor who knew Tennov at the University of Bridgeport but did not assist in her research, and Duyen Vo, a graduate student, suggested that limerence is similar to obsessive–compulsive disorder (OCD) and substance use disorder (SUD). They presented work to an American Association of Behavioral and Social Sciences conference, but suggested that much more research is needed before it could be proposed to the APA that limerence be included in the DSM. They began conducting an unpublished study and reported to USA Today that about 25% or 30% of their participants had experienced a limerent relationship as they defined it.<ref name="usatoday">Template:Cite news</ref> Wakin has stated that his concept involves people in relationships, where a person is obsessed with their partner to the detriment of the relationship, even to the point of a breakup.<ref name="usatoday" /><ref name="potentgrip" /><ref name=":24">Template:Cite web</ref>

Limerence and romantic love (also called passionate love) have been compared to OCD in general since 1998, according to a theory invented by other authors.<ref name="fisher1998" /><ref name="leckmanmayes" /><ref name="proximateandultimate" /><ref name="co-opted" /> This was partly based on a theoretical comparison between preoccupation features, like worries about a family member being harmed and a need for things to be "just right".<ref name="leckmanmayes" /><ref name="co-opted" /> This is also sometimes paired with a theory involving the neurotransmitter serotonin, but experimental evidence for that is ambiguous.<ref name="fisher1998" /><ref name="fisher2002" /><ref name="proximateandultimate" /><ref name=":28" /> A 2025 study found no association between SSRI use and obsessive thinking about a loved one or the intensity of romantic love.<ref name=":28">Template:Cite journal</ref> Neuroscientist blogger Tom Bellamy has argued that limerence is distinct from OCD on the basis of psychological and neurobiological differences. OCD is characterized by compulsions to perform rituals that ease some type of fear, whereas limerence initially starts with a period of joy and only reaches a stage of anxiety when a pair bond cannot be formed.<ref>Template:Harvnb</ref>

Helen Fisher has commented on Wakin & Vo in 2008, stating that limerence is romantic love and that "They are associating the negative aspects of it with the term, and that can be a disorder."<ref name="usatoday"/> Fisher is one of the original authors to compare limerence to OCD, and has proposed that romantic love is a "natural addiction" which can be either positive or negative depending on the situation.<ref name="fisher2016"/><ref name="fisher1998" /> Fisher stated again in 2024 that she does not think there is any difference between limerence and romantic love.<ref name="madlyinlove"/>

In 2017, Wakin has stated that he feels that brain scans of limerence would help establish it as "something unlike everything that has been diagnosed already",<ref name=":12">Template:Cite news</ref> but brain scans have been described by Fisher's team since as far back as 2002.<ref name="fisher2002" /><ref name="usatoday" /><ref name="beam-limerence-fisher"/><ref>Template:Cite web</ref> In Fisher et al.'s original brain scan experiments, all participants spent more than 85% of their waking hours thinking about their loved one.<ref name="fisher2016" /> Wakin also claims that a person experiencing limerence can never be satiated, even if their feelings are reciprocated.<ref name=":12" /><ref name=":24" /> Tennov found many cases of nonlimerent people who described their limerent partners being "stricken with a kind of insatiability", and that "no degree of attentiveness was ever sufficient".<ref>Template:Harvnb</ref> According to Tennov's theory, the intensity of limerence diminishes with reciprocity, and it's prolonged inside a relationship when the LO behaves in a nonlimerent way.<ref name="conceptions-of-limerence" /><ref>Template:Harvnb</ref> Other mainstream authors have stated that obsession inside a relationship when it's a problem could be related to self-esteem and an insecure attachment style.<ref name="acevedo2009" /><ref>Template:Cite web</ref><ref>Template:Cite news</ref><ref name=":110">Template:Cite journal</ref>

In the 1999 preface to her revised edition of Love and Limerence, Dorothy Tennov describes limerence as an aspect of basic human nature and remarks that "Reaction to limerence theory depends partly on acquaintance with the evidence for it and partly on personal experience. People who have not experienced limerence are baffled by descriptions of it and are often resistant to the evidence that it exists. To such outside observers, limerence seems pathological."<ref name="Tennov 1999 x"/> Tennov states that her studies suggest limerence is normal,<ref>Template:Harvnb</ref><ref>Template:Harvnb</ref><ref>Template:Harvnb</ref> that it's too often interpreted as "mental illness", and that even those who experienced limerence of a distressing variety were "fully functioning, rational, emotionally stable, normal, nonneurotic, nonpathological members of society", "characterized as responsible and quite sane". Tragedies such as violence, she says, involve limerence when it's "augmented and distorted" by other conditions.<ref>Template:Harvnb</ref><ref>Template:Harvnb: "Data is not available relating limerence to increased jealousy or violence. It is my guess, but only that, that very intense sexual jealousies may occur outside the limerent state. Famous fictional cases do not conform to the expected pattern, e.g. Flaubert's Madame Bovary and Hollywood's Fatal Attraction. But limerence combined with psychopathology may produce results that escaped inclusion in the data base."</ref>

In a 2005 Q&A, Tennov was asked if limerence could ever lead to a situation like the movie Fatal Attraction (which has been called "obsessive love"), but Tennov replied that the movie seemed to depict a caricature.<ref>Template:Harvnb</ref><ref>Template:Cite book</ref> Most romantic stalkers are an ex-partner, erotomanic, have a personality disorder, are intellectually limited or socially incompetent.<ref name="fisher2016" /><ref>Template:Cite journal</ref> One writer who investigated the phenomenon of limerence videos on TikTok in 2024 wrote that it seemed to her that the many videos created by the relationship coaches there were actually about social media stalking rather than having anything at all to do with limerence.<ref name=":19">Template:Cite web</ref>
