DV is NOT ACCEPTABLE!
You need to get this jerk away from both you and your child. How many more times will it take for you to realize that? The next time you may not be able to ask for help after he attacks you.
It sounds like you are not married and are living with your folks. He needs to get kicked out of the house and you need to go Non Contact IMMEDIATELY!!!
Please get the help you need before it happens again.
