What should I do ?

That sounds like a lot more than you just being pregnant currently. Figure out what you need to do to be able to leave with your child, can you save to move out? I know it’s not simple as just leaving but you need a plan and get going with it. You both want different things and sounds like you want out and so does he.

Leave. Plain and simple. U protect your babies. Get a lawyer involved if needed. Get the cops involved if needed as well. Just leave. It sounds like a dangerous situation ur in, so first, u need to leave. Figure everything out second.

For me personally, I wouldn’t be bringing another child into the world if this was the state of my relationship. You said, “he acts like he cares about me.” Except that your post contradicts that completely. He’s not acting like he cares about you. It sounds like if you keep the baby, your relationship will be over. And tbh, if you don’t keep the baby to appease him, the relationship would most likely end soon anyway. You’ll eventually resent him for that decision, if it’s not the one you wanted. If you’re set on keeping the baby, I would immediately figure out a plan to leave. The sooner you do it, the quicker you can heal and be able to show up 100% for your son and your new baby. If there’s a will, there’s a way. You just have to figure out what that path looks like and how you will support you and your children without him.
