love is to rose and limerance is to...

I'm writing up my paper for human sexuality class and in trying to find accurate definitions I ran across this word: limerance. Click on the link to its definition in wikipedia under my new words list and tell me what you think. Is there such a psychological state that is something more than a crush? Maybe infatuation isn't the right word for lingering desire for someone? Do you think you've experienced limerance? Comment and tell me what you think.
