What should I do?

So, I just broke up with this guy that wasn't nice to my friends, or me. Apparently he was going to break up with me on Wednesday and I broke up with him on Tuesday. He said it was because I was moving and he didn't think he could do the long distance thing. I found out that it was a very painful reason. I don't want to get into it. I got really mad at him. My friends think I'm overreacting and are mad at me. When I tried to talk to them about the painful thing, they just dismissed me. So, I broke up with him and he was upset that I beat him to it? I guess. He texted a group chat (that I'm not on) really mean things. He called me a brat, a freak, a piece of crap (but the other word), and a girl dog (If you know what I mean). So, I was really upset, especially because we had agreed to just be friends (And I know that breakups are normally clean but I wan't expecting that. Later that same day, he sent me a text saying just "sorry" and I replied with "For?" and then he replied with "You just seemed mad that I was happy" like, okay I guess, but can we reword that please? Anyway, I just ignored it, ate some dinner and then the next morning I read a text from him saying "I'm just sad that I don't have anyone to cuddle anymore" which is so random, especially after what he texted. Then, I found out that the long distance thing was just a cover for the real reason. He said that he thought that I was going to be lesbian next year and he didn't want to date a not nice word. He texted that to one of his friends who also happens to be like really nice to me. That's the really painful reason. I felt extremely hurt and even more angry. When I wanted to talk to my friend about it she said "Nah, me and A (that'll be his nickname) are gang gang" so what I take from that is that she is on A's side of the breakup. I just said "Okay.... I guess" I told my other friend and she was kind of mad. So, I brought his sweatshirt to give back to him and I was like "Should I just like throw this (the sweatshirt) in his face and then punch him?" I laughed and I get that violence isn't the answer, but I was just joking. My friend was like "I think you need to calm down. You're overreacting" I'm just hurt because I thought that my friends would be on my side and I know that one of them is on A's side and idk who's side the other one is on. I have a couple friends that are on my side, but the two I talked about were like, my life, like the people I would miss most, and I was just really hurt. She (We'll call her Ash) didn't exactly say that she was on his side, but how else am I supposed to take that ("Me and A are gang gang")? Oh yeah. You low-key hated him while we were dating and now you guys are all buddy buddy? What happened? She's also mad at me for being mad at her friend (C) for hitting on my bf while we were dating. Now, that was a misunderstanding (wrong A) and I apologized to C about it and C accepted it, but Ash is still mad at me.
