Tennov estimates, based on both questionnaire and interview data, that the average limerent reaction duration, from the moment of initiation until a feeling of neutrality is reached, is approximately three years. The extremes may be as brief as a few weeks or as long as several decades. When limerence is brief, maximum intensity may not have been attained. According to David Sack, M.D., limerence lasts longer than romantic love, but is shorter than a healthy, committed partnership

Limerence is a state of mind which results from romantic or non-romantic feelings for another person, and typically includes intrusive, melancholic thoughts and/or tragic concerns for the object of one's affection as well as a desire to form or maintain a relationship with the object of love and to have one's feelings reciprocated. Limerence can also be defined as an involuntary state of intense desire.
