If a relationship and treatment of you is that bad in the beginning, it has no where to go but downhill. it is supposed to be happy and exciting in the beginning and there might be some issues in the future. It’s not happy from the start so I’d say you have to be prepared for it to go worse and stay bad. Sad situation

Also you are teaching him that it’s ok to abuse and mistreat you. So there’s no reason for him to ever stop or improve. I recommend for you to see a therapist. Not for him. For yourself. To help you understand why you are ok with it. He’s not your family or even a spouse. He’s a recent boyfriend. There’s no reason to tolerate mistreatment. None.

So I’d try to work on figuring yourself out. Not him. You can’t change him
