I think i'm addicted to infatuating over somebody

I don't do it on purpose. But I seem to get over someone, then find another person the next. Although my feelings are intense, and I'd want the best for them, it must be infatuation.
Apparently there's a little 'high' you get over that person (brain chemistry ... details unknown). Also, it almost gives me something to concentrate on/look forward to when I sometimes feel misanthropic.
I don't know, it just feels good.
