Have you ever found yourself thinking about someone constantly and replaying conversations, imagining a future together, feeling euphoric when they respond but devastated when they don’t? Psychologists say this an overwhelming emotional state may not actually be love. Instead, it could be limerence, a powerful form of romantic obsession that can dominate thoughts, moods and behaviour for months or even years.The concept has recently exploded across social media and relationship discussions, with many people realising that what they once believed was deep love might actually have been a psychological phenomenon rooted in infatuation, uncertainty and idealisation. Experts say understanding limerence can help people recognise unhealthy relationship patterns and ultimately build healthier emotional connections.
What is limerence? Definitely, not love
The term limerence was first coined by Dorothy Tennov, an American psychologist who studied romantic obsession in the 1970s. Her research found that many people experience an intense state of longing that goes far beyond an ordinary crush. Tennov described limerence as a psychological state characterised by obsessive thoughts about another person, emotional highs when affection seems reciprocated, intense anxiety when it is not and idealising the person as a perfect partner.
This Psychological Phenomenon Makes You Think You’re in Love
In limerence, the object of affection (often called the “limerent object”) can become the centre of someone’s mental world. Researchers say that this experience is surprisingly common. Some studies suggest that more than half of the people may experience limerence at least once in their lives. Yet despite how common it is, limerence is still widely misunderstood and frequently mistaken for genuine love.
Expert insight: Why limerence feels like love
According to British psychologist and academic researcher Giulia Poerio, Associate Professor of Psychology at the University of Sussex in the United Kingdom, limerence can look almost identical to the early stages of falling in love. Poerio has discussed limerence in academic interviews and psychology podcasts studying intrusive romantic thoughts. In an interview on The Longing Lab psychology podcast discussing her research on romantic obsession and mind-wandering, she said, “Limerence involves persistent, intrusive thoughts about another person and a strong desire for emotional reciprocation.”
If limerence is not love, why do some people become emotionally obsessed with someone
However, the key difference emerges when the feelings are uncertain or unreturned. Poerio revealed that the experience can feel overwhelming because intrusive thoughts about the person dominate the mind. “It’s a real cognitive invasion of your mind,” she explained, adding that the emotional reward makes the experience feel addictive.This mixture of anticipation, hope and uncertainty can create powerful emotional cycles, similar to the reward patterns seen in addictive behaviour.
The neuroscience of romantic obsession
Researchers studying limerence, explore the neurological mechanisms behind romantic obsession and share that limerence is closely linked to the early biological stages of attraction, when brain chemistry creates intense emotional highs but they explain that long-term relationships cannot survive on limerence alone.
Not Love? Psychologists Say This Intense Feeling Could Be ‘Limerence’
Dr Helen Fisher, Biological anthropologist and Senior Research Fellow at the Kinsey Institute, Indiana University, has extensively studied the neuroscience of romantic obsession. In Fisher’s research interviews and lectures on romantic attraction and brain chemistry, she has pointed out, “Romantic love is one of the most powerful brain systems humans have evolved.” She noted that the early stages of attraction can resemble addiction in the brain.Eventually, the experts highlight that the relationship must evolve into affection, communication and respect, all the things that we associate with healthy, mature love. When that transition does not happen, the emotional fixation can intensify rather than fade. Experts warn that severe limerence can lead people to reorganise their lives around the person they desire. At its worst people may lie about motivations or seek indirect ways to remain emotionally connected.
Why uncertainty makes limerence stronger
Psychologists say that one of the most powerful triggers of limerence is uncertainty. Unlike stable relationships, limerence often thrives when the other person sends mixed signals or when the relationship is complicated or impossible. Since the desired person sometimes appears interested and sometimes distant, the emotional reward system in the brain becomes highly activated.

Small gestures like a text message, a compliment or a brief moment of attention can trigger powerful bursts of excitement but when attention disappears, the emotional crash can feel equally intense. This unpredictable cycle is why limerence often feels both exhilarating and exhausting.
Modern dating may be fuelling limerence
According to relationship psychologist Dr Alexandra H Solomon (Clinical psychologist and faculty member at the Northwestern University; licensed marriage and family therapist), modern technology may be intensifying limerence. Social media platforms and dating apps allow people to constantly observe the person they desire. Solomon has written extensively about obsession and romantic idealisation in modern relationships. The relationship psychology commentary and lectures from Solomon’s work on modern intimacy assert, “When we don’t truly know someone, we often fill in the gaps with fantasy.”

Explaining why limerence often involves idealising a partner, he elaborated, “The apps and social media provide access to inputs and data about the object of your desire.” In previous decades, people might have lost contact with a romantic interest after rejection. Today, however, social media creates endless opportunities to revisit the person’s life online. This can reinforce the obsessive thought patterns that characterise limerence. Instead of fading naturally, the emotional attachment may grow stronger through constant digital exposure.
How long does limerence last?
Tennov’s original research suggested that limerence usually lasts between 18 months and three years, although in some cases it can persist much longer. During this period, people experiencing limerence often report difficulty concentrating, emotional mood swings, intense daydreaming about the person and interpreting neutral actions as romantic signals.Since the experience can be so consuming, it may interfere with work, friendships and other relationships. Yet many people remain unaware of what they are experiencing.
Why people confuse limerence with “true love”
One of the biggest reasons limerence is misunderstood is that it shares many features with romantic love. Both involve strong emotional attachment, excitement and longing. However, psychologists say that there are crucial differences.
- Love tends to develop through shared experiences, mutual support and emotional stability.
- Limerence, on the other hand, often thrives on fantasy and idealisation.
Instead of truly knowing the other person, the limerent individual may fall in love with an imagined version of them. That imagined connection can feel deeply real, even if the relationship barely exists in reality.
Can limerence be overcome?
Mental-health professionals insist that recognising limerence is the first step toward breaking free from it. Therapeutic approaches may include:
- cognitive behavioural therapy (CBT)
- cognitive reappraisal strategies
- reducing contact with the person
- challenging idealised fantasies
Bellamy also recommends limiting exposure to the limerent object, including avoiding their social media profiles. These steps can help interrupt the emotional feedback loop that fuels obsessive thinking. Limerence is a powerful emotional experience that can feel indistinguishable from love but psychologists say that it is fundamentally different.While love grows through mutual understanding and stability, limerence thrives on uncertainty, fantasy and emotional obsession. As discussions about limerence spreads across social media and relationship psychology, experts hope that greater awareness will help people recognise the difference because understanding limerence, they say, may be the key to escaping cycles of romantic obsession and finding healthier, more fulfilling love.
