My current boyfriend and ex-boyfriend are in the middle of an ongoing argument that takes place on facebook with messages. My ex and I still talk every now and then but it's just as friends. My boyfriend hates him for all the hurt he's caused me in the past; he knew how much I loved my ex, how much he hurt me, he's seen me cry about it and feels the need to protect me as I'm much too nice and refuse to see the truth.

I was trying to play peacekeeper, trying to get them both to relax, ignore each other, as I've seen the messages they send. But last night my ex sent my boyfriend something and it hurt. He said that he knew my boyfriend was only mad because he hurt me, but that he had a good reason to leave and cheat on me and my boyfriend will find out soon enough what he's talking about. I read that and my jaw just dropped.

For my ex I've been absolutely forgiving. I've been giving him advice on new relationships, being a shoulder to cry on when his step-dad is being abusive. I've been there for him when he not only kicked me to the curb but emotionally beat me for months after we broke up.. And instead of him at least saying that he's sorry and all that was in the past, he says he was justified and my boyfriend is going to see how much of a horrible person I am and do the same? This has only given my boyfriend more of a reason to yell at him and I can no longer say that he's a good guy underneath.

I know I'm an absolute doormat and probably this is my fault but what am I supposed to do now? I'm not going to be talking to my ex for a long time, and I really don't understand why on earth he would say something like that. I can't deny that he's a jerk and convince my boyfriend to leave it alone anymore. I know that this is really immature of them both, but we're all young (middle - late teens). That's not much of an excuse.. but I don't know what to do.
