Just want to start with I'm sorry this is so long.

I'm currently 24, my bd and I have been off and on for the last three years, almost four by the time DS is here in December (if not earlier due to some medical problems)
When things between us are good, they are really good and everything goes ...good lol.
But when things are bad, we typically have an argument and then won't talk for x amount of days (typically no more then 3)
But the reason we fight is because he gets on "meetme" and "pof". He swears up and down that he only talks to people on there and not often, that he doesn't exchange numbers or inappropriate conversation. Now considering I've been through his phone and can never find ANYTHING, and when I look at his messages on those sites -there isn't anything inappropriate I try to not argue with him, as he feels we shouldn't be together because or the arguments. He doesn't want us arguing around DS which I totally agree with. But I feel like if he's truly not doing something messed up that he would just get rid of them? We currently are not living together as well so I constantly find myself thinking any time he doesn't have me over there spending the night that he's doing something "bad".
I also just wanted to add a few things he's said to me during these arguments. One being that he didn't want to have kids (this was an "accident" to him obviously) but that he wants to be in his sons life and etc. but that he doesn't even think about sex with other people (we still have sex) because he defiantly does not want two kids with two different women. -but yet he won't commit because we argue about the dating websites...now am I crazy or does that just look like a big ass excuse?! It keeps us fighting cuz I'm on edge all the time but he won't get rid of them to stop the fighting...? It's seriously the ONLY thing we argue about.
Side note. Part of me honestly thinks he's just "trying to work things out" (even though clearly he can't be with the dating websites) so that way I don't go through courts and we just handle things ourselves. I'm going no to be taking him to at least mediation because I just feel deep down I can't trust him unless he proves himself.
I read through some threads and couldn't find anything similar to this stupid limbo he wants to play. Any advice? Or similar stories?
