Break up again

I posted a little bit ago that my bf broke up with me out of nowhere and I was heartbroken. Well we ended up getting back together after a month apart and after 2 weeks I broke up with him today after we got into a fight. He's always been a little mean and I've told him when he hurts my feelings but he always said that it wasn't his problem if I couldn't take a joke. I tried to talk to him about it today but he got defensive and said he was going to change. All I asked was that he be more considerate when he talks to me but he was cert clear that his answer was no. Looking back he's been gaslighting me for many things. He was currently gaslighting me about moving in with him. I wasn't sure yet and he kept bringing it up so I said okay but when I said I wasn't sure again he told me I should've thought about it before I said yes. Keep in mind we still don't know where we would move to and it would be in the future. When I broke up he said I didn't even give him a chance to do anything or change but he made it clear that he wasn't going to change when we were fighting. He straight up told me he wasn't going to stop talking to me that way. I am so heartbroken but I know that this is for the best. I just feel so hurt though. If he had just agreed to compromise we’d still be together but I just don't know if that's what I want. I could really use some encouragement right now or something letting me know this is the right decision bc I just wanna run back.
