Limerence is an involuntary state of intense longing for one particular person, a term coined by the psychologist Dorothy Tennov in her 1979 book Love and Limerence. Someone in limerence thinks about the other person constantly, swings between euphoria and despair over small signs of interest, and craves having their feelings returned, often without wanting to feel this way.
The idea has found a new audience thanks to Curry Barker’s horror film Obsession. Bear, the main character, cannot bring himself to tell his co-worker Nikki how he feels, so he snaps a novelty “one-wish willow” and wishes she loved him more than anyone in the world. The wish comes true, and her devotion turns possessive and frightening. As the Guardian observed in an interview with Barker, the wish traps Nikki in a non-consensual relationship that robs her of any agency. The film has taken more than $520 million worldwide and returned to cinemas in 4DX for one night on 14 October, according to horror news site Bloody Disgusting, and viewers are still arguing about where intense love ends and obsession begins.
It is a fair question, and real limerence is far quieter than a horror plot. In a qualitative study published in The Qualitative Report, Lynn Willmott and Evie Bentley of the University of Sussex described it as an acute onset, unexpected, obsessive attachment to one person, which they noted is rarely reported in scientific literature. Longing for someone who does not feel the same can also take a real toll on mental health, and the constant checking and doubting can look a lot like relationship OCD, which can make ordinary love feel impossible to trust.
What limerence feels like
The Cleveland Clinic describes limerence as an involuntary state of intense obsession, fixation, and attachment to another person, often called the “limerent object”. The feelings are usually not returned, and they can surface after an unresolved relationship or an unrequited crush. Common signs include:
- Intrusive thoughts: Daydreams and replayed conversations arrive uninvited and are hard to switch off.
- Mood that hangs on their behaviour: A friendly message can bring euphoria, while a slow reply can bring despair.
- Idealisation: The other person seems flawless, which the Cleveland Clinic calls the halo effect.
- Checking: Repeatedly looking at their texts or social media profiles becomes hard to resist.
- Fear of rejection: Worry about being left behind or ignored sits alongside the longing.
- Physical symptoms: Some people notice a racing heart, sweating, loss of appetite, nausea, or poor sleep.
Albert Wakin and Duyen Vo, in a 2008 conference paper proposing a model of limerence, define it as an involuntary interpersonal state that involves intrusive, obsessive, and compulsive thoughts, feelings, and behaviours that depend on perceived emotional reciprocation from the person of interest. That last part matters. In their model, uncertainty is the main driving force, and limerent reactions tend to fade once there is complete certainty, whether that means clear reciprocation or clear rejection. Until then, every ambiguous signal becomes something to analyse.
If you are wondering whether this describes you, these limerence signs can help you tell it apart from an ordinary crush.
How limerence differs from love
Early love and limerence can look almost identical. Wakin and Vo argue that the two cannot be told apart in the first stages of a relationship, but that they separate over time. In love, the early intensity and absorption tend to settle, making room for a more stable, intimate, trusting, and committed bond. Limerence, in their view, is a state that is necessarily negative, problematic, and impairing.
Biology hints at why the early stage can feel so consuming. In a 1999 study in Psychological Medicine, Donatella Marazziti and colleagues measured the serotonin transporter in the blood platelets of 20 people who had fallen in love within the previous six months, 20 unmedicated patients with obsessive-compulsive disorder (OCD), and 20 controls. The people newly in love had significantly lower levels than the controls and did not differ from the OCD group. It was a small study, and it does not mean love is a disorder, but it fits the everyday experience of a mind that keeps circling back to one person.
A useful rule of thumb is to look at where the attention goes. Love, even when it is intense, tends to include genuine interest in the other person’s well-being, their own wishes, and their right to say no. Limerence is mostly about relief from your own longing, and it can continue even when the other person has shown little interest at all.
Why some people are more prone to it
Attachment style seems to play a part. In a classic 1987 study in the Journal of Personality and Social Psychology, Cindy Hazan and Phillip Shaver asked adults to describe their most important love experience. People with an anxious or ambivalent attachment style described love as involving obsessive preoccupation, a strong desire for reciprocation and union, emotional highs and lows, extreme sexual attraction, and jealousy. The authors noted that this group provided a close fit to Tennov’s description of limerence.
Clinicians draw similar links. The Cleveland Clinic lists insecure attachment, trauma, low self-esteem, and heavy social media use among the factors that may make people more vulnerable, and it notes that limerence may be associated with anxious or avoidant attachment.
Rumination is the other thread. In Willmott and Bentley’s study, the main themes people described were ruminative thinking, free-floating anxiety and depression fixed for a time on one person, and a sense of the self falling apart. The authors also observed that people in limerence were attached to both a real and an idealised version of the other person, which they suggested may relate to attachment anxieties. Going over the same scenes again and again does not settle the uncertainty. It tends to deepen it.
Is obsessive love disorder a real diagnosis?
No. “Obsessive love disorder” is a phrase you will find all over the internet, but it is not a formal diagnosis. As a medically reviewed explainer from Medical News Today notes, it is not listed in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), and there are no specific diagnostic criteria for it. The Cleveland Clinic says the same of limerence, which is not an official medical diagnosis.
That does not make the distress any less real. Obsessive feelings about a partner or a crush can sometimes be a sign of a recognised condition, such as OCD, a personality disorder, or erotomania, a delusional belief that another person is in love with you. That is why it makes sense to talk to a professional rather than diagnose yourself from a list of online symptoms.
Why you cannot make someone love you
This is where Obsession lands its sharpest point. Bear gets exactly what he asked for, and it is a nightmare, because a love that has been forced on someone is not love at all. The law in England and Wales captures the principle well. Under section 74 of the Sexual Offences Act 2003, a person consents if they agree by choice and have the freedom and capacity to make that choice. Take away the choice, and consent disappears with it.
No one has a wish-granting willow, but the fantasy behind it is familiar. Limerence can feed the belief that enough persistence, grand gestures, or guilt will eventually change the other person’s mind. In real life, that can shade into pressure, monitoring, or unwanted contact. Respecting a “no” or a lack of interest is not giving up on love. It is the only basis on which love can exist.
How limerence ends
Limerence does fade. According to the Cleveland Clinic, it can last anywhere from a few weeks to a few years, and some people experience it more than once. It often ends when the feelings are returned and a real relationship replaces the fantasy, or when it becomes clear that a relationship is not possible and the attachment gradually falls away. A few practical steps can help it on its way:
- Name it without judgement: Recognising the pattern as limerence, rather than proof of destiny, can take some of the heat out of it.
- Cut back on checking: Searching for the person online and rereading old messages keeps the cycle going, so start by limiting the easiest habits.
- Set boundaries: Less contact with someone who is not showing up for you gives the longing less to feed on.
- Widen your circle: Time with friends and family offers connection that does not hinge on one person’s reply.
- Get support: The Cleveland Clinic notes that cognitive behavioural therapy (CBT) can help people understand the causes and change the behaviours that keep limerence going.
When to get help
It is worth seeking help if limerence is taking up hours of your day, affecting your sleep, work, or relationships, or leaving you anxious or low. In England, you can refer yourself to NHS talking therapies for problems such as low mood, worry, and OCD without seeing a GP first, as long as you are registered with a GP and aged 18 or over (16 or over in some areas). You do not need a diagnosis to ask for help.
If you are on the receiving end of attention that feels obsessive or frightening, you do not have to manage it alone. The National Stalking Helpline, run by the Suzy Lamplugh Trust, offers advice on safety and the law on 0808 802 0300. If you are thinking about suicide or feel unable to keep yourself safe, the NHS advises calling 111 and choosing the mental health option, or calling 999 or going to A&E if a life is at risk. You can also call Samaritans free on 116 123.
FAQs
- What is the difference between limerence and love? Both can feel intense at first, but love usually settles into trust, intimacy, and care for the other person’s well-being. Limerence stays focused on uncertainty and the need for your feelings to be returned, and some researchers describe it as problematic and impairing.
- How long does limerence last? It varies. The Cleveland Clinic says limerence can last from a few weeks to a few years, and it tends to fade once the feelings are returned or it becomes clear a relationship is not possible.
- When should I get help for limerence? Speak to a GP or refer yourself to NHS talking therapies if it is disrupting your sleep, work, or relationships, or leaving you anxious or low. Get urgent help if you feel unsafe.
- Is obsessive love disorder a real diagnosis? No. It is not listed in the DSM-5 and has no diagnostic criteria, although obsessive feelings in relationships can sometimes point to a recognised condition such as OCD.
- Is limerence the same as OCD? No, but they share features. Researchers have drawn parallels between limerence and OCD, and one study found similar serotonin transporter levels in people newly in love and people with OCD.
