The kid's got issues. The problem is you keep feeding him all of this by accepting his requests. My most recent ex tried to add me on Myspace about 50 times and I denied the request each time. I think that's something you will have to learn to do, or this will never stop. Don't hate yourself over it, just change it. Stop talking to him cold turkey, or it's going to get worse. And I mean this in a sincere way because I know how it is. You have to save yourself from this pain... You can't keep letting it happen, and even if you don't care that he has that girl anymore he will try to use you and get you to feel sorry for him and become his girl again. Not a good thing. Hope it all works for you.
