Need some help

I've been married for 11 years. We have 2 kids and are pregnant with our 3rd. My husband has had a temper since our daughter was born almost 11 years ago. He yells and screams at the kids. He gets so mad he will punch the door or wall. I've almost filed for divorce 6 months ago because I couldn't take it anymore. Then he started to change. Things were going great and amazing. We found out I'm pregnant which he didn't really want. Well now the anger and temper towards the kids is back. I'm already emotional being 6 weeks pregnant but seeing my kids cry just breaks me even more. I don't know what to do. I actually said I hope my baby dies so it doesn't have to live like this. I'm just at a loss. 😢😭
