Husband just hit me?

So my husband and I were play fighting in bed which we do quite a lot and he bit my shoulder and as I turned around to push his head off I accidentally hit him in the nose. I apologised immediately and said 'i didn't mean to hit you' about 3 times and he got up, pinned me down on the bed, punched me extremely hard in the arm and screamed in my face 'if you ever f***ing do that again'. I have honestly never seen such anger in someone's face. I understand I probably hurt his nose but it was a complete accident.. he has a history of anger problems but that's down to his PlayStation, I don't know if this is bad or not.. I got really scared and went to sleep on the sofa but he wouldn't leave me alone saying he's sorry and didn't mean to get angry with me.

Please could I have some advice? I don't want to tell my family as I don't want to blow something that might be minor our of proportion..
