Need help deciding if I made the right decision

So basically I’ve been with my bf for about 2.5 years and at first it was just lust and then we developed feeling for each other and he had lost his job around that time so I was helping him out with money and food etc. things were pretty good in the beginning we always had a good time and he helped me when I was vulnerable when things were going on in my family etc. so I loved him a lot. He told me he didn’t want to be in a relationship but he didn’t want me to be with anyone else so a lot of lines were blurred but he pointed out that when we become a couple he becomes very territorial or w.e. So I’m thinking it can’t be that bad but it was. He would accuse me of cheating, blow up my phone with messages and calls while I’m at work it even got to a point where he would video call me at work to see my surroundings to see if I’m actually there and still accuse of me of being somewhere else. I told him on multiple occasions that was not the case and that I can’t drop everything I was doing to pick up his phone calls while I’m at work. Then he started calling me names like hoe and smut and that I suck dick while I’m pretending to be at work. I told him to not talk to me like this multiple times I even took a break from him because I thought he was being overwhelmed with my presence. Then when he would get really mad he would start slapping me but I would hit him back and he would pretend to hit me so I would flinch. But he would always apologize and say he’s sorry and never do it again and I believed him always and went back just to get beat up physically and mentally and I gained slot of weight and he also brings it up but I’m a stress eater. But I love him and want to be with but I just don’t want him to treat me this way. He says he loves me but he won’t stop treating me like this. So He broke up with me like he always does and thinks being nice to will make me come back. I love him but idk what to do?
