I hate my life

So I made the mistake of taking my son's father back 2 months ago after he cheated and had another kid, I got a restraining order against him because he put his hands on me, courts got involved and so did DCFS. So I found out that hes been messing around with the one he cheated on me again, I'm currently pregnant he told her I was pregnant and staying with him but he added lies as to why I'm staying with him because he "doesn't want to lose either of us". So the other girl got mad because he lied and came over here saying why was I here, next thing you know she threatens with letting my baby's social worker know were here when we clearly can't be around the dad! Which she did and the social worker showed up telling me I had to move she's been nice about because I literally have nowhere to go and she wants us to work it out, I don't want my baby taken away. Its clear the dad doesn't care about us I'm just so fed up with this drama I want him out of my life but its gonna be hard.
