He is emotionally manipulating you by saying he would be dead.
That is not constructive communication. I see it as blackmail.
If this were me, the next time he said anything that is abusive, I would call the police and have them take him involuntary mental hospital. Because he is an obvious danger to himself if he would say that hed be dead without you.
And then i would file for protective order for you and your child so when he is released, he cannot come back to your home.

Im sorry i am so blunt, but i worry for your safety. This is very serious, and im sure scary for you. This is a man you love, who is treating you awfully. I would call it abuse.
Maybe reach out to a local support for domestic abuse victims for guidance. Or an attorney?

And please keep us updated. You are pregnant and you have a child relying on you. Ill pray for you tonight.
