limerence 

The actual definition above is incorrect, the correct definition is an infatuation or crush that lasts at a much longer time span. A crush is for a short duration of time, while a limerence may last for months, years or even a lifetime.

P.S. "Limerent" is not an adjective, check dictionary.com while you're at it
