Albert Wakin, a professor of psychology and expert on limerence, defines the term as a combination of obsessive-compulsive disorder and addiction – a state of “compulsory longing for another person.” Professor Wakin estimates that five percent of the population struggle with limerence.

Limerence involves intrusive thinking about another person. It is often confused with love addiction but there is a fundamental difference. In love addiction, people want to replicate the feeling of falling in love again and again, while those experiencing limerence are focused on feelings for a specific individual.

Limerence is not the same as being in love. It is smothering and unsatisfying with little to no regard for the other person’s well being. In healthy relationships, neither partner is limerent; they do not struggle with constant, unwanted thoughts about their partner. A person experiencing limerence has feelings so intense that they rule every waking moment causing everything else to be left in the background. The person also tends to focus completely on the positive attributes of the “limerent object” and avoids thinking about any negative aspects.

Professor Wakin says, “It’s an addiction for another person. And we find that the obsessive-compulsive component of it is extremely compelling. The person is preoccupied with the limerent object (the subject of their obsession) as much as 95 percent of the time.”
