"Limerence is an involuntary cognitive and emotional state of intense romantic desire for another person. The term was coined by psychologist Dorothy Tennov to describe the ultimate, near-obsessive form of romantic love. Limerence is sometimes also referred to as infatuation, or is colloquially known as a crush, but in reality it is something much different. In common speech, infatuation includes aspects of immaturity and extrapolation from insufficient information, and is usually short-lived. The concept is an attempt at a scientific study into the nature of romantic love. Limerence can often be what is meant when one expresses having intense feelings of attachment and preoccupations with the love object. It can be experienced as intense joy or as extreme despair, depending on whether the feelings are reciprocated."
