First of all.. GET OUT OF THERE! With the children of course.
I would suggest going to family, like your parents or siblings.
I am shocked… Shouting can happen sometimes, but afterwards one apologizes – and physical violence is completely out of the question. Your husband has crossed all lines, you have to get away from him before he causes more serious and permanent harm to you or your children. They are already severely damaged, and so are you – physically not permanently (I hope), but mentally you are all severely hurt and you will need a lot of time and help to build a new life.
But the first and foremost priority must be that you GET AWAY FROM HIM. Nobody benefits from you staying with him.
