Honey, the MOST important thing for you right now is to stay safe.!
If that means staying away from your husband, then that is the right thing for you to do. If you don't want to do that for yourself, then you need to do that for your baby. You are the only one who can protect your child right now.
God does not want you to live in a situation where you are constantly fighting and being harmed. He does not want you to put yourself at risk. He wants what is good for you, and being a with a man, even your husband, who is capable of hurting you is not what is best.
IF he truely repents and gets healed up, not just help, but actually displays proof of change, then I would say return to him. But this evidence of change needs to be consistantly present for a duration of time, not just words spoken, not just a few good deeds, but lasting evidence, without being prompted. He has to choose repentance, and he has to work to get well, or he can't be trusted.
Forgiveness on your part toward him does not require trust. It if foolish to trust someone who is not trustworthy. You would be putting yourself at risk for further harm, and not only yourself, but also your child.
Speak with people in person: a pastor, a counselor, godly family and close friends. Keep them up to date on all the circumstances. Allow the people who know you well and love you to speak into your life, and let them help you to make good choices. We are to seek godly council.
Stay safe. Give it time. Wait on the Lord to move and to tell you what to do.
Blessings and grace to you!
