Limerence, a term coined in the 1970s, describes an intense, involuntary, and often obsessive attachment to another person. Unlike a typical crush or romantic love, limerence can be all-consuming and distressing, with sufferers experiencing intrusive thoughts and a longing for reciprocation that may not involve a desire for a relationship.
Neuroscientist Tom Bellamy, who experienced limerence while happily married, describes it as an altered state of mind. 'It feels fantastic at first, like a natural high, giving increased energy and optimism. That's why it's addictive,' he says. However, when unmanaged, limerence can become scary, leaving individuals feeling helpless and out of control.
Psychologist Dorothy Tennov, who first identified limerence in her 1979 book Love and Limerence, noted that it is involuntary and can occur once or multiple times in a person's life. An average episode lasts between 18 months and three years. Uncertainty is a key driver: limerent people become stuck in a state of longing and hope, fuelled by a 'glimmer' of potential reciprocation.
Ian Tyndall, a cognitive-behavioural psychologist at the University of Chichester, explains that limerence can cause significant distress, leading sufferers to neglect eating, sleeping, and personal hygiene, and even disrupt their ability to work or maintain other relationships. In some cases, it may escalate into harmful behaviours such as stalking.
Since 2020, global search interest in limerence has risen, along with online discussions about when love tips into obsession and how to manage it. Researchers emphasise that while limerence is involuntary, recognising it is the first step toward regaining control.
