I have been with my BF for a year now, we don't get along, we fight, he is treating me badly

I've been with my boyfriend for a year now. We don't get along anymore. All we do is argue. And he will call me out my name and treat me really badly and now it's getting to the point when he gets mad at me he will put his hands on me. I over looked it at first because he would apologize but now I notice it keeps happening. I'm scared and tired of being hurt by him. He blames me for our relationship problems when it's not all me. He feels I should listen to him and not have an opinion but I feel I should be able to voice my opinion in our relationship I don't know what to do anymore a big part of me still loves him but at the same time.I feel this isn't going to work anymore and I'm tired of being sad and making people believe I have the perfect relationship. Things are going to far and I'm scared someone will get hurt.
