basically, something happened in a group chat where my (now ex) gf and a mutual friend of ours made a joke which I kinda took the wrong way. I didn't wanna say anything because honestly it wasn't a big deal at all but my best friend did on my behalf. I didn't ask her to do this, nor did I want her to, but it's resulted in my gf wanting to break up and me getting into a huge fight with my bff.and the worst part is that i don't even think I'm upset? I've been with my girlfriend for 4 years and have known my bff even longer than that, but part of me just feels relieved to have cut them out of my life. it doesn't feel right being so nonchalant and i feel like i should be more upset.
