I hate all of my friends (IRL) except for like 5 people

I'm so mad rn, I have a friend group which has about 20 of us maybe a little less but that's besides the point, Either way there's this one guy, I'll just call R since idk if the asshole has access to this, R is a self centred asshole and only talks about himself, he get obsessive over women or anyone who remotely looks or has been a woman, At one point he asked me out and that obviously didn't go well, Ever since R asked me out I've only grown to hate him more and more, every day feels like a try not to punch him in the face or put him in his place. Yesterday at about 3pm where I am, I was speaking to another friend M, M was repeating some silly phrase over and over again as a joke and I asked "why do you keep saying it over and over again" which is besides the point as M was going to answer R decided he wanted to answer even though i wasn't talking to him and he wasn't in the conversation, I immediately said "I didn't ask you" because I very clearly didn't and he want involved. So today it currently 10 am so about 20 minutes ago I was speaking with R's Boyfriend T. Me and T are friends and he was telling me that R is scared of me because I was aggressive and rude to R apparently. And I've just logged onto Discord to see that he's removed my roles from the server were in. Mind you he didn't talk to me about it, He didn't try to make me aware of his emotions. He just took the most dumbest way out. So now I'm planning on either leaving the server or Confronting him about it. I'm getting really sick of his BS. 

I'm sorry for ranting its just that i cant talk to any of my friends about this due to the fact that most of my group doesn't know about R's shit side.

-Thanks
