Why do you bother to talk to him if all hes gunna do is make you feel bad? Just ignore his and his friends calls. It sounds to me like your not over him, and hes not over you...
If you were over him, you wouldent care about him having a girlfriend, and you wouldent care about what he had to say about you. I always claimed I hated luis when I was mad at him. I was just...Mad.
And if this guy was over you, he wouldent have tried breaking up you and your new guy. He wouldent bother calling you, or having his friends call you. Hes trying to get under your skin, and it seems to be working.
I think that you should tell him your pregnant. That could change alot of things. Maybe he knows your pregnant, and is being a problem cause he thinks "someone else got my girl pg" I know but a bit of your situation, but from what I do know, it sounds like you both still have feelings...

I will always have some kind of feelings but I don't care about his girlfriend I am happy for the both of them. I also know for a fact he doesn't know about the baby because no one knows except me, my doctor and my parents. I haven't told anyone and I am not big enough yet for anyone to notice. I feel better now though since I got it all out. Thanks

I totally understand where you're coming from. But if hes the father of your child and he doesn't know and finds out later it can be far more worse. He sounds like an immature little punk, but he still has the right to know and if he finds out later on he could use it against you and try to get custody, even if you think he wont want anything to do with the child, you have no idea.
