I feel like a d! ck for treating him like that what shall I do?

I deeply regret my actions and feel ashamed of how things turned out. For a couple of months, I was talking to a guy, unsure if we were a good match. My intention was never to lead him on, but his overly possessive behaviour made me feel trapped. He constantly demanded explanations for my whereabouts, hated my friends, and criticized my behaviour. I stopped hanging out with friends and he kept on asking for my location but I refused to share my location, feeling it wasn't healthy given his past actions. He also would make me feel like I'm going crazy by saying something to me then when I ask about it he would say that he didn't say such thing and I was hearing things.

Recently, we made out for the first time, but shortly after, I told him I didn't think it would work out. I have a lot going on emotionally and mentally and need to focus on myself. He said I broke his heart and shouldn't have kissed him if I felt that way. He then insulted me, saying I'd never get married, end up like my divorced sister, and called me derogatory names.

I apologized for not communicating clearly and for initiating the makeout, but he won't accept my apology. I feel terrible about how I treated him and am unsure of what to do. He won't accept my apology and I a truly sorry.
