Of course you can cope with 2DC! you know that! ((hugs))
You can't stay in this situation, really you can't.
You can not ever, and I mean ever make him change. he hit you once, he has now given himself to hit you again. These things only ever escalate.
Counselling will help YOU recover from a violent and abusive relationship, but it will never, ever make any difference to HIM.
Relate and other relationship counsellors often refuse to take cases where violence is an issue, as they know that these kinds of abusers use the counselling as another weapon to beat you with.
There is one option. One sole option and that is to leave him.
I'm sorry to be so blunt, but he is now technically dangerous, and you have DC to think of, and yourself. You could waste the next 10 years trying to reason with him (as I did) or you can accept the fact that your safety and that of your DC is more important than a relationship with a violent drunk.
You have all the evidence you need to make the decision.
if he so much as looks at you again, call 999 and get him removed. get legal advice and get them to get a removal order, and then you can stay in the house.
Otherwise, get a bag together, money, passports, documents, photos, clothing and get out, get somewhere safe and stay there.
If you own your own property, you can get a charge put on it to protect any equity.
Do not waste time thinking you can make a difference. Nothing you did caused this and nothing you could ever do, think, be or say could ever change it.
I know that is a hard pill to swallow, but you don't have the luxury of time, your situation is now unsafe.
