[Limerence] is characterized by intrusive thinking and pronounced sensitivity to external events that reflect the disposition of the limerent object towards the individual…. Physical contact with the object is neither essential nor sufficient to an individual experiencing limerence, unlike one experiencing sexual attraction…. Limerence can dissipate once reciprocity is established, and is characterized by uncertainty and anxiety…. Limerence can be longer-lived than transient forms of romantic feelings such as infatuation and puppy love, enduring for months, or even years in the absence of knowledge about reciprocity….
This pretty much describes my life.
