Why am I STILL so ridiculously Infatuated with a girl despite knowing I'll never be In Love With her?

Infatuation and love are two entirely different things. I'm infatuated with Jessica Biel but I don't love her. Well of course I've never met her either. Lust (infatuation) is a physical thing where as love is an emotional connection. So enjoy your infatuation - most of the time it's harmless. Now when you do fall in love you might want to put aside that infatuation. LOL
