You go non verbal when scared, not an unusual reaction. My stbxh has a similar effect on me. Even if you were doing it on purpose his response would still be wrong and abusive. He's been physically violent to you twice now, his behaviour is escalating. It's your house and you're not married, if you are in the UK I believe that means he has no right to the house so you can change the locks when he goes to work tomorrow and shut him out legally. Not the case where I live. If you can do so call the police tomorrow, change the locks.
For now keep your phone on you in case you need it and think about your options for a safety plan if you need to leave in hurry. I know how much you want to think that's not necessary but it is. I'm sorry he's putting you through this, NONE of this is your fault, you didn't make him do it, this is all him. It feels surreal and wrong that someone you trusted and loved can turn out to be a danger to you, but he is a danger to you all. I wish you all the best and strength to get through this. You are stronger then he's made you feel you are.
