So has all this happened while you were pregnant or was it like this before?
Sounds pretty miserable and awful - quite frankly. I can understand why you are upset.
I would a) stop the screaming and the fighting. That's not good for you or the baby and b) if he won't stop the controlling behavior, I'd go see a counsellor (myself) and get advice on how to proceed.
The whole spreading lies thing - that's just warped. I can't imagine my husband doing that.
Do you have friends or family you can reach out to? I'd start there. Stop the fighting on your end though - just don't engage. Walk away. Leave the room if you have to.
