Agree. Be strong. While it is still early, abort the baby. (I am sorry to say this. But it is really unfair to the baby to born with a father like this.) Divorce. Don't think how long it will take to divorce. Just start the divorce process ASAP, no matter how long it will take. You shall find an apartment and move out now.
If necessary, find help from organizations helping woman who is in an abusive family.
