Love, Infatuation or Obsession?


I've never felt like I was in love but I've liked people. I guess I really don't know what its like to be in love. Recently however there is this one guy that I can't stop thinking about. I jump at every opportunity to aid him in whatever eay he wants. I don't see it as he's using me and when he's around other girls I don't get jealous. Am I in love, infatuated or just obsessed with him? P.S this has been going on for about 3 years now
