It sounds like he is really struggling with his sexuality. He probably doesn't hate you. He probably actually likes you but that is seriously interfering with his image of himself as heterosexual so he is tearing you down to try to convince himself that he doesn't like you.

The truth of the matter is that you can’t force him to come to terms with his sexuality or speed up the process. These things take time and you owe it to yourself not to wait for him. You really don’t need a man in your life who is going to tear you down, criticize you, or be physically violent with you. None of that is even remotely okay regardless of what struggles he may be going through. Maybe someday he’ll come to terms with his sexuality and will be a great, loving boyfriend for you, but you deserve so much better than a guy who will love you "maybe someday". You deserve a man who knows what he wants, likes you 100%, and makes you feel like a king. Right now, this boy is not him.

Personally, I think you should seriously distance yourself from him. Let him work out his own problems far away from you because this guy is abusing you and leading you on and that is not okay. If someday several years down the road, you two meet up and he seems like a changed man who has come to terms with his sexuality, then yeah maybe you can give it a try again. But certainly don’t wait for him because this boy is abusive and you deserve better than an abusive SOB who will love you “maybe someday”.
