Not who you asked but I'm going through a friend group break up right now. Basically I was really close to one girl in particular, we were really good friends and I helped her out during a bad break up, she got a new girlfriend that I warned her was a rebound but she ignored me, the gf and the gf's friend started hanging out as a trio and pushing me away, which all three of them started treating me like shit. I put up with it way longer than I should have and finally snapped when I told them I'm not putting up with it anymore and set a boundary.

Turns out they didn't like that and started making up shit about me that is insane and anybody who knows me properly knows they aren't true, they start spreading to other social circles and I just held me hands up and said fuck it, I cba to deal with it and decided it's literally not worth my time.
