The complete and final devotion of your actual being to one single person other than yourself in a romantic fashion. Limerence creates a spiritual image with almost divine traits of the person you love that may have nothing to do with their actually existing person. It is a state of mind, fully captivating the heart, soul and spirit, that might last until the end of your life. All your actions, every step you take shall be done for that person you love only. In every hour, on every day you will think of only him or her. The other person's rejection of you will also be your downfall.

A floaty, manic, excited, feeling that often arises after meeting or spending time with someone who you are recently attracted to. Also, a fluttering heart, or butterflys in the stomach are symtoms of the feeling. It is similar to infatuation except that it lingers, is usually less lusty and does not have the same negative connotation. Also is usually a temporary state, unlike love. Often thoughts of the person are deep and engaging, resulting in day dreaming. The word was originally founded by a Psychologist in the 1970s

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.

Wiki it yourself, you'll see.

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

Noun. Adj. version "limerent."
The sheer shining moment and a brief period of time when a person falls blindly and intensely in love. Limerence is a temporary condition that fortunately goes away, allowing the love-er to come up for air and see a person or situation for what it is rather than what they want it to be. Limerence is being high on love. This condition makes people believe that they have found their soulmate.Usually followed by a crashing blow - the manic becomes depressive.
