Please help 😭

Ladies, I’ve recently gotten out of a bad relationship. We dated for 8 months and for the most part things started out amazingly. Shortly after we began dating, I was told some very rough things about his past. I knew that he had a terrible childhood and that it bothered him everyday. I tried getting him to go to therapy to work things out, but he refused every time. This problems from his childhood had left him with many adult issues, such as terrible anxiety, depression, manipulative, overthinking, anger, abusive, etc. I tried for eight months to help him, but he never wanted to help himself. About five months into the relationship is when major issues started happening. Anxiety between both of us began (i never had bad anxiety before this), he would get frustrated with me for no reason, yell at me, mentally, emotionally, and verbally abuse me, he would slam his head against metal doors, throw things, slam doors/drawers, etc. (It got so bad that his brother even confronted me with his concerns about it too) I kept pushing it off knowing that he was struggling in life and kept trying to help him. Unfortunately, everyone else has left him in life, so I was the only person he had. I did everything I possible could but it was never good enough. I took a huge beating and it started affecting my mental and physical health. I just wasn’t me anymore. So I asked for a break. After he finally agreed, we went our separate ways. He wouldn’t leave me alone for anything, so I blocked him. Then, he started making fake profiles to stalk and talk to me over social media. My family and friends have been very worried about my safety since all this started happening five weeks ago. Anyways, I am a very caring, big hearted person, and even though he has torn me apart and stomped me into the ground, I still care. I feel awful for leaving him since he has no one else, but he takes no blame in what he has done. He turns everything around to be someone else’s issue. And I had to leave before losing all of my mental, emotional, and physical health. I couldn’t keep putting myself in the situation that he had me in. But y’all, I’m really struggling because I’m taking care of myself first. But, then again, he shouldn’t have been that way with me in the first place. I gave him numerous warnings that I would leave if he kept treating me that way, but that never stopped him. Honestly, it kept getting worse, and it scared me. So anyways, do you guys think I did the right thing by getting out of the situation before it became something way worse?? Or should I have stuck with him and tried more to help?
