Am I the bad friend?
so in simple words There used to be this friend A shes great and all but she has always said thing that hurt me deeply like really badly but I always shutted up about it due to my mental issues back then being very poor. the trigger point was when she asked for her red flags and I said she judges people to fast and she said “Oh my parents just taught me that” and then I also said “And sometimes your words hurt you know?” and she replied. with “That’s just you.” so that hurt. a lot and I stopped trying to talk to her and just gave dry responses avoiding her completely at school. then she got upset and texted me trying to make me say ANYHRING but I was done and I was immature and reckless so I said nothing. i could tell it hut her badly but i didnt wanna hurt her I just don’t want to be her friend anymore. apparently she told her sister. whom attacked my brother then tried talking to me about it only to not listen to me at all. so I didn’t try to fix things with them too. Then I caught wind that she told this issue to a lot of my friends too. bc her friends were technically my friends too. that hurt me even worser bc this ended up confirming my suspicion that she would vent to everyone. that’s when I felt even worser and more in guilt and hated myself futher on ward. these weeks I just continued ignoring her. we had a project to finish BUTI had an alright day so I was treating her like I would treat any classmte. but in the end she sent a gmail saying she doesnt want me talking so casually with her so I said Alright Yeah. and left it. I don’t know what to do I’m leaving the school soon anyways. it’s hard to move bc she’s in most of my classes and near my seat as well. and mostly bc Im not mentally stable still. any tips or suggestions to get throguh? and opinions on what I could have done better or if I was the asshole in the situation?
