Is he really over me or playing me?

Hey everyone. Well here’s my question. My ex boyfriend and I broke up about 6 months ago. And I have been single for 5 and a half months. My ex has a new girlfriend now (which is one of my friends) they have been togther for about 3 months now. I still talk to my ex sometimes on msn. But our conversations always end up in arugement. He is still… mad at me for breaking up with him and hurting him, but I just dont understand why… he has a girlfriend and says he really loves her, but when ever I’m talking and say a compliment and stuff he ALWAYS thinks I’m trying to break them up, and I’m not. Is he really over me. Or is he playing me I don’t know.

Ohh and I kindof have feelings for him still :( and I dont know why

HERE IS MY SECOND QUESTION.

I was talking to his new girlfriend, and she was saying that one of our friends called her a homewreakers, and said if I wanted she would break up with him so that him and I could get back together and I told her “no he’s your boyfriend and if you guys break up I dont want it to be because of me”

IS SHE BEING LOYAL???

Thanks Guys xox
