Accidentaly In Love

I can't stand falling back into a love trance. Not that he's making me do that it's just me. I'm just not really sure what to do because there's a part of me that still love's him and there's a part that doesn't. The girl he cheated on me with broke up with him yesterday. And now he's comming back to me asking me back. And after what he did to me I don't really know if I want to ever go back to him. But I have all of these mixed emotions that seems like they just keep messsing with my head. One of my friends has gym with him so she always tells me what goes on and everything and yesterday she told me about that so I was like ok whatever what he did to me I can never forget for the rest of my life. But these past few days we've not been together has just been like a love strukk to me. But I have noticed everywhere I go he's there and it's like he's all around me and I can't get rid of the images. My friend also told me that he's been asking about me ever since we split. And now it's got me wondering if he's just trying to make me mad or if really wants to come back to me. It's crazy. What I did was wrote him a note this morning telling him how I felt about the whole situation and that I told him I still had feelings for him but I can't use those feelings because I am still hurt. And plus he's already got another girlfriend so I think it's pretty pathetic to come back to me asking me to take him back and I say no because I have a right to and he goes off and just does another stunt again. And that if I was to ever get back together with him I don't want hurt again. I don't know it's just really crazy. And maybe one day he will come to his senses.

If any advice let me know.
Thanx
