I don’t get it…

I was in a situationship with my coworker. It’s been a year and a half. Everyone on here would say he was controlling, abusive, and would hold onto me as a backup in case his other side things didn’t work out. He would talk about my clothes, friends, family, coworkers, kids, call me names, scream over little things, throw things, etc. He broke up with me in beginning of May and said “we’re too toxic”. Then came back a few days later, only to do it again 2 weeks later over a “he said, she said” situation. Then came back a week or so later and said we could have sex still. That lasted about a week. Then he called me a dumbass and said we should stop talking at all last week. I said okay and he put a sad face and said I frustrate him. Then just blew up my phone until I talked to him and acted like nothing happened. Then the last couple days he’s been talking about how we shouldn’t have sex. At first I would agree and he’d say nevermind. Then yesterday he says he thinks I have feelings (even tho he usually has to double text me for us to talk? I also even told him that I was talking to someone for a few days when we werent fucking so I felt over it). So now he says we’re “just friends”. I said i wanted to switch job so that we don’t see each other or talk anymore. He said he “doesn’t want it to just be goodbye and we never talk or see each other he just wants something healthy” and is pushing me to “ focus on myself”. He said before that he doesn’t want me dating anyone he knows, anyone we work with, and he doesn’t/didn’t want me posting anything about other dudes or even just knowing.
