Is this gaslighting or just immaturity? I need help figuring out my relationship

I (25F) and my bf (25M) have been together for 6 years. We live together and basically have our whole relationship. Just to give a back story, Our relationship has always been pretty bad. he’s been caught texting other women and flirting recently, he’s destroyed our house that only I clean, by dumping soda every where on the floor, knocking over the liter box, spitting everywhere, etc. recently he broke my tv and kicked our door in destroying it, when I locked myself in there to hide from him and his outburst. He will call me names like obese, tell me if I had more estrogen maybe I would act more like a women ( I can’t have kids), so he definitely gets very verbally abusive. So I decided I was going to leave, I live super far from my family and plan on moving back to my hometown. Before I 100% decided I was leaving, I asked him to go to couples therapy with me. He refused, I asked for a conversation at least to see if there anyway we can save the relationship, he said “ I’m not begging for you”. Now that I am leaving, he seems to be basically pushing me out the door, said he is getting a air bnb this weekend, and that I’m playing mind games and I just need to leave. But I can’t, I have to wait for my family members to come help me move. Anyway, I told him I have not been perfect, I get attitudes or I do things I regret yes. I am not perfect and I know I have a lot of things I need to work on and work through. I’m no saint. But I admit when I am wrong, he doesn’t. I don’t think I deserve this treatment at all. I know he isn’t the only one to blame, but I told him I don’t destroy his stuff, threaten him, mess the house up, etc, when I’m mad. I may yell, call him names, but I never get physical. Now he’s guilt tripping me and saying I never loved him, and I’m just giving up and this is so random that I’m leaving and I must have been using him. When that’s not the case at all. This hurts so badly, I wanted to have a future with him, I really do love him and it’s hurtful for him to say I’m just leaving because I don’t love him and I used him, instead of taking accountability for everything he’s been doing to me and realizing that’s why I’m leaving. Not because I want to, but it’s become apparent that I HAVE to. I just don’t want to regret leaving. I want to know I’m making the right decision. I know there’s 2 sides to every story, and this is only my side. But I just need some advice, I know I’m not alone here, I know this has happened to other people. If you could go back to the time in your life when you was going through this, and was having a hard time leaving, what would you say? Any advice would be nice on how to handle this and how to move forward.

TL;DR: My boyfriend never takes accountability and constantly blames me. I’m not sure if I’m overreacting or if I need to leave.
