So I'm just sick of this, My best friend gets boyfriends and they fight a lot so I always have them both calling me or talking to me online, so I try to help them out explain things get them both to calm down and whatnot, but Now I'm in the middle and now she's accusing me of trying to ruin her relationships because I ruined my life by having a child and dumping tony. I'm so hurt I don't know what to do, I'm sitting here in tears because of her.
see this guy that shes dating right now she lives with him because her mom kicked her out so they fight a lot, and I always get the calls telling me so and so did this from both of them, well this time he called me and she was @ my house and listening he said he felt like he had to babysit her all the time that he didnt want a babysitting job he wanted an adult relationship (he's 22 she's 17) So she then procedes to go to their house and take her stuff and leave. So I have him calling me asking what happened and why the hell I told her what he said and shit. Which I didn't because she was listening. And then she tells me she didnt like him that she just needed a place to stay, which she then told him. And now I'm being accused of telling him that when it was her who told him!!! and so now I've been shouted at and told I ruined my life by having a child and dumping tony. And apparently I'm trying to ruin hers... ugh im so hurt I can't believe she'd ever say that to me.

Get yourself out of the middle - now. Just cut off ties with both of them until THEY resolve things.
You dont need "friends" like that. Get away from them for awhile!
This does not sound like a good friend to me. This sounds like someone who thinks that the world revolves around her.
I think you should tell her to go solve her own problems and to leave you alone.
