Could be any number of reasons, but sounds to me like she found somebody else. Sorry that happened to you.
Oh i guess i also should've mentioned that she recently got screwed over by her ex. He up and left her and took some of her things with him. She mentioned him at times when we were spending time together too. So now that i think about it.. chances are he's back in the picture or something. I'd rather it be that than it be something was wrong with me. She obviously found me attractive since she had no problem kissing me and stuff. But anyways. enough of my thread hijacking lol. Also, thanks Marie. I'm slowly but surely getting over the hurt.
