Me and my boyfriend were walking by his ex, and then he told me he would talk to me later, so I said bye, and saw him walk over towards a tree and watches his ex. She has a new bf, and it looks like he is watching them. Then he walks back to me and suggests that we sit right in front of her. Then he puts his arm over my shoulder and keeps making me laugh. Is he using me? He swore that he didn't love her anymore, but is it that? Or is it just some stupid boy teen hormone?!?
