Sometimes I wish I'm a little tougher

I can't even recall how many times I've told myself to forget bout him and move on...why can't I just let go my feelings for him? It's not that I don't know he's a player. Was I really just infatuated with him as Jen said a while ago? I'm quite certain I don't love him but I do know I like him a lot. Is there any differences? Even I get confused thinking about it..
