AITA for the telling my friend to stop following me in games

I (F15) and my friend T (M14) have known eachother for a couple years now, and overall he’s stuck by me considering how emotional/dramatic I can be sometimes. Recently though, i’ve been hanging out with my online friends more often, me and T never meet in person anyway and he does have other friends than me, so I didn’t see the problem. Other than that i’ve spending time to myself after having an extremely long depressive episode which lasted for about 3 years. Me and my online friends tend to play games on roblox, and as I also play with T on there, I have him friended. He’s also met my online friends and had the option to be friends with them, but he chooses to actively upset them and piss them off. More recently, my friends have started to dislike him, which I decided was fair considering how he treats them, and he began joining us in games, and when we call him out for watching us from the distance, he continues to say he isn’t in the game and tells us we’re photoshopping or waffling about something he has no clue about. This past week, he’s started acting really snarky and rude, and has said many hurtful and offensive things directly to me, he’s also began calling me names like love, etc, which i’ve already explicitly told him make me uncomfortable, especially considering i’m a lesbian. It’s now to the point all of my friends dislike him and want to cut him off, and have all left group chats that he’s in today after an argument where he continued to aggravate them. After my friend left the gc due to the frustration, he asked if she’s feeling okay, and I replied saying he should’ve just stopped. He said there was nothing started to stop, said it was odd, then said bye. This has been going for months now, and all of my friends are actively treating him the same way he’s been treating us, supposedly worse imo. T thinks i’m excluding him, but the rest of my friends say that it’s his fault for constantly trying to frustrate us. Today though, my friends all snapped at him and made a group chat without him. I would be okay with this as it would stop the conflicts to an extent, but every time this happens T always releases the backlash onto me. I want everyone to get along but I don’t think that’s possible anymore and I’m not sure what to do now other than wait. But I wanted to know if i’m in the wrong here. AITA? (Sorry if everything is a bit muddled, I can give more context if needed.)
