Am i getting fucked over?

So yall, the last mth, my husband and i argued a lot, hed tell me he wants a divorce, he talks about cheating on me, how its super easy for him to cheat. Hed talks about having sex w other women. Having a side chick, so if i leave, he wont be fucked cause he already has her. And yall, our arguments have NOTHING to do w cheating. Hed tell me he made a mistake marrying me. He wants out, but he never leaves. Like he wants me to be the one leaving him, or something. Hed tell me that when we divorce, i need to take all the kids w me, i can deal w the struggles, while he live in peace by himself, and start over. Im a sahm and if we divorce, i wouldnt be able to support the kids and i... he said he wants me to feel the pain and he wants me to struggle, so ill take life more serious.

We had sex in that mth, after all our arguments were resolved. He came inside wout telling me, and talking to me about it first. I didnt want another baby w him. We argued again, and he said those things to me again.

Sigh, i found out my pregnant. And it saddens me a lot. This will be our 3rd child, and i hate myself for doing this. I feel like hes purposely doing this to fuck me over and ruin my life.

What am i to do?
