Abortion advice

I'm not sure what decision to make. I have 1 son by a emotionally abusive man and I'm 7 weeks pregnant with our second child. I realized that he is using this As a form to control and destroy me. He cheats, lies, manipulates, trailblazing, and much more. I got back with him to try and be a family for our son but he hasn't changed and he is treating me much worse. Right now I want absolutely nothing to do with him. And I'm considering abortion as a form to escape him. Abortion is inhumane but this man wants to make me miserable with and without being with him. I want nothing to do with him. But babies are a blessing, but how can I enjoy my blessing with him always hanging something over me as a way to control and destroy me? I already feel grief for killing my unborn child. And I feel unhappy for keeping it. He also isn't a good father. Any advice?
