Stand up.
You're a grown person, You can't let him hurt you, Tell him "This doesn't mean I will love you any less than usual, But, If you don't accept me, Then you just have to deal with it.", The world is not just gonna do whatever THEY say, Sometimes, They just have to go with the flow.
You aren't telling them "I will hate you now", You're telling them "That's who you've been living with for the past years".

If you still live with him, try to move out when you’re 18. Until then, keep holding on! If you can move out, the sooner the better.

beat the shit out of him when he's asleep. He can't control the person you are. Runaway to a supportive family member, or if he keeps verbally and physically abusing you, tell someone about it. you don't deserve to be treated this way because of the way you are
