You have parents or other family? Friends? Neighbors? People from work or school or church or the gym even, who you trust and can help you?
Contact them. Tell them you need to move out of where you are currently living. Tell them it's temporary but you're not sure of how long that means, but you would greatly appreciate their help. If you don't want to talk about it, tell them that you don't feel like talking about it.
Then pack your things and get the hell out of there.
This is not going to be the last time this happens. Abusers (yep, that's what this is) may swear up and down that they've changed, it was a mistake, they were drunk, they didn't really mean it, yadda yadda yadda it is all so much noise.
It'll happen again.
Actions without consequences are permission.
Do not give him permission to do this to you or to your child. If nothing else, see it as a protective measure for your child.
You've already been bruised. He's already pounded your head against a wall (have you been checked for a concussion?). Eventually, he'll give you or your child a permanent injury.
Abusers are also really, really good at being sweet as pie when they have to apologize and make up. To quote Depeche Mode, "Never again is what you swore the time before."
It'll happen again. And again.
You're terrified and freaked out. Want to be that way for decades? Of course you don't.
Contact people who you trust. Have them help you leave if you need for them to or you will be in danger by the simple act of leaving.
Is this breaking up with him? Why yes, yes it is. Yes, even if you still love him. He does not love you. These are not the acts of a loving person.
Does this mean he can never see his child? Not necessarily. But insist on supervision for visits if you can.
Be an advocate for your child if you currently cannot or will not be one for yourself. You and your child will both be far better off if you do.
Life doesn't have to be this way.
