What do you think should i do?

[Kemi]

I fell in love with a guy about a year and a half ago. Long story short, it became an abusive relationship, and I ended up with a sprained wrist and multiple bruises and scratches. He seemed like my knight in shining armor, when he turned out to be the opposite. We stopped talking for a while, and then he showed up in my life again, asking for my forgiveness and me back. He promised me he would never do that to me again, and he regrets it all. I didn't bat an eye when I turned him down, but now he keeps bringing up our relationship and all this stuff about it. I recently found out he has locked texts and pictures of them because he doesn’t want to forget. He keeps bringing up times when we were together, and it's just like a nonstop guilt trip. I do still care about him, but I’m more concerned about not possibly ending up in the hospital. Any help?
