He isnt going to change, so you will have to protect yourself and your baby. Only talk to him when necessary. The Verbally Abusive Relationship by Patricia Evans saved my life after 31 years of verbal abuse.
Quite often abusers use projection...they project onto YOU, the feelings they have about themselves. He probably feels HE is a failure. They hate themselves.,and want you to be as miserable as they are. They don't care how you feel or what you think, so talking to them is useless.
Every time you are under stress...verbal abuse....your body releases cortisol and cortisol damages your immune system...leaving you wide open for all kinds of illnesses. This is not good for you or your baby.
