warning: long read 

This was a couple of years ago but I still often think about this. My ex-best friend of a couple years and I were in a pretty large friend group at the time for context. 

Anyway, my friend, lets just call her ‘A’ told me she was talking to this guy in our college, she showed me the messages and he seemed pretty cool. They would meet up often and I tagged along once or twice, so the guy, A and I started a group chat to talk about life. We talked a lot for a few months and grew closer but I felt A was drifting from me after years of being close best friends. I obviously knew something was up as the guy and A started to talk to me less and less. 

Fast forward to my birthday party where I invited the large friend group, including A. I asked her if she had been talking the guy lately and she said more than before. I asked to play a game on her phone and she reluctantly gave me her phone, instead I went on to their messages to see what they had been talking about and discovered paragraphs and paragraphs of them just taking shit about me. I really wanted to just  burst with anger but I kept reading and found her saying how much she just wanted me to die and the guy saying “ I should just kill myself.” I was disgusted, raging but I asked her to leave outside without causing a scene. 

Later on I messaged both of them saying that they should no longer speak to me or look at me,  saying I was finished with them and that I was going to block them on all social media. I then told my friend group what she had done and they all immediately stopped talking to her. I feel guilty as she lost all of her closest friends because of me, I’m not sure if should’ve told them but it was such a big thing that they had done that I had to have someone to vent and cry to. AITA for this?

summed up: found out friend wished for me to kill myself, told all our friends what she had done, she lost her closest friends.
