I would not try to talk to him about it.
The first and most important issue is for your safety.
Please don't antagonize someone who is drinking and prone to violence, no good will come of it.
YOu are in an abusive situation, everything else takes a back seat and can get sorted out once you are safe.
I am sure others will be around soon with more advice.
I personally suggest that right now you have a phone on you at all times, call 911 if you feel at all in danger, you may want to consider an exit plan , if there is a womens resource center nearby, call them, it's a good place to start. They may be able to help you.
Take good care, please keep posting, we care about you.
