So for a little background info I (22F) have known my friend K (25F) and my "friend" S (28M) for about a year now and they've known each other for about 2 or 3 now I think. They've always budded heads mostly for that her mental disorders cause her to blow up easily and him not understanding basically anything he does wrong.

Now for what happened last time. S and K got into an argument that basically started during a game of Arena League of Legends. She had a rough day and times before told S that she doesnt like to be told how to play. He then proceeded to give some advice in what she should do. She calmly stated that she didnt really appreciate this and before she could elaborate why, he blew up saying "seriously? XD it was just some advice" and everything escalated from there and both were in the wrong from that point on.

Now I spend about 5 hours trying to explain to S that what he said was basically downplaying her feelings and he didnt get it, saying things like "I have freedom of speech and I can voice my hurts whenever I want too!" (He's not American before y'all comment that) and stuff like "it was just a small thing I dont get why she was upset". I tried for way to long and felt my braincells dying. Talked to my boyfriend about it and he agreed that S seemed like a prick and agreed that K couldve handled it better too.

Now 2 days later, I wake up to a text with screenshots asking why I was rude to his friend. Mind you, I have had 1 conversation with this person and had no clue who she was at first. She had helped me figure out some medical stuff, I conversed, thanked her and asked questions but never spoke to her after that. S had asked her if we were still talkin, she said no and badmouthed me sayin I was cold, didnt thank her and overal didnt enage, making her uncomfortable. He and I quote said "oh wow, I... didnt expect that. I still talk to her from time to time, but maube thats just how she is." Having known me for a year, youd think hed know me by now and maybe ask me what happened. So I expressed my hurt that he didnt defend me, went very defensive about the situation and I just told him after an hour or so to leave me alone, as I had to stream per my schedule. During my stream I get a screenshot with " ^{^} " showing how the same girl who badmouthed me ADMITTED she lied to him and then basically calling me dramatic. To say I lost it is an understatement. Then getting comments like "what did I even do now" and "because I shared how someone actually gives a shit about my feelings and respects them." So I lost it even more, so trying to hold my composure on stream, I texted him that if i didnt care I wouldnt have spend hours on tryna mend his friendship with K and called him a socially inept person, and told him this was the reason I was blocking him.

Now K was watching my stream and noticed something was off and offered to play with me. After about 30 minutes or so, I misclicked something in my OBS and opened my viewer list, seeing S his name there, so I told him on stream to leave, he did not. I asked again and he said "okay ill leave if you want" or smt like that. Not long after that the girl that badmouthed me showed up in the viewer list. Now this is where I may be the AH, but a viewer asked what was happening and at that point I just explained the ENTIRE situation. Not my best work, but it was so much that it just flew out.

So AITH?
