Parents disapprove of SO

So I know I’m probably going to get judged on this but I honestly don’t know what to do. I’m 22, my ex is about to turn 26. We’ve dated on and off for almost 2 years, me being the one to break up with him every time except once. My problem is my parents HATE him. Like last time we were together my mom wouldn’t let him come to family functions like Christmas or anything. We’ve been broke up since February and we’ve recently been considering get back together in the future. We both agreed that we wanted to take things slow. I honestly want to spend my life with him. The reason my parents don’t like him is because when we first started dating he had bad anger issues and would cuss me out. Since then he has gotten a lot better. He’s went to anger management classes and everything for it and last time we were together we argued some but he didn’t have angry outbursts like cussing me and stuff. Also, after we broke up, I accidentally kicked him in the balls because he wouldn’t get out of my face and I was trying to push him away with my feet and he fell to the ground and went to punch the ground and hit my leg instead and it left a bruise. My mom is like my best friend and I’ve realized that a lot of the reason they don’t like him is because I’ve only told them about the bad stuff and not about the good stuff. My parents don’t want me to get back with him, I currently own a mobile home that’s on my mothers land and she’s forbid me from letting him come to my house. I’ve tried to tell her that he’s changed and that right now we’re not together we’re just talking and taking things slow and about all the things that make me love him and how I’ve dated other people and how I’m fine being alone but nobody makes me as happy as he does and how he’s the only person I want but none of it is making a difference. Also a big issue is my mothers boyfriend who doesn’t like my ex either. And I realize this post is kind of just rambling and probably confusing and extremely long so if you’ve read it all, thank you. I just don’t know how to get my parents to like him again. They don’t even have to like him, I just don’t want them to try to kill him if he comes to see me.
