Limerence = Having a crush – IDEAS

http://en.wikipedia.org/wiki/Limerence

limerance is an involuntary cognitive and emotional state in which a person feels an intense romantic desire for another person, the limerent object.

Limerence can often be what is meant when one expresses “having a crush” on (or infatuation with) someone else although limerence, unlike a crush, can last months, years or even a lifetime.
