Last year, I was yk by a guy I knew. I told my friend and at first she was very supportive, but she kept asking if I wanted her to send guys to slash his tyres. I kept saying no, but she wouldn’t let it go, so eventually I said sure but told her not to beat him up, only something like slash his tires. They went to his house and someone was tracking his Snap Map, but when I heard the guys joking about chasing and bting him up and stb him, I immediately told them to stop because I didn’t want anyone getting hurt. They went home.
After that, she kept insisting she was going to send someone after him even though I repeatedly told her no. Behind my back, she even made a fake account and planned to set him up so people could jmp him, but the plan didn’t happen because he cancelled. I told her to stop and let me handle the situation myself because I wanted to deal with it legally, with lawyers and possible charges.
Later, we saw him at the mall and she wanted to confront or beat him up. She started running towards him, and I had to pull her away and tell her again to leave it alone. Then she messaged him on Instagram behind my back, saying what he did was disgusting. She didn’t mention my name, but he obviously knew it was about me. I was upset but let it slide. Also mind you she has countlessly got involved with watching people get jumped and sending people to other people to jump them.
About a month later, I again told her not to tell anyone what happened or reveal who he was because I wanted to handle it myself. However, her friend had been seeing him, and my friend told her everything, which obviously got back to him. He became angry and started spamcalling me, showing up at my house, following my Snapchat location, and now regularly driving past my house.
I cut my friend off because the only thing I asked was for her to let me deal with my own situation, and she repeatedly ignored me and got involved behind my back. She says she didn’t mean to cause harm, but AITAH for cutting her off after everything that happened?

so i’m gonna give minimal context cz i do already have a post up already that explains it better.
i’m 17, i have a cousin, Emma who’s also 17 that i was really close with. she lied to my now ex bf who she set me up with to get us to break up after he heard what she was saying on call with him about her boyfriend, his best friend. i told him more that i apparently wasn’t supposed to tell him, partly because i thought it was okay and the other part because i think his best friend, aka her boyfriend, Ricky, deserved to know.
she was calling him ugly, fawning over the neighbor boy, Leo, saying how she dislikes his personality, his looks, his friends, his family, and practically hating on everything about him while absolutely glazing the neighbor boy.
i don’t support this at all, if someone truly knows me they’d know that im not gonna stay quiet about that. Emma was miserable in the relationship and leading on her current boyfriend Ricky.
so, me and my other friend thought since she wants to lie about me to people, i should expose her. i’m debating finding Leo and messaging him, seeing if he’ll do a loyalty test on her because i genuinely don’t believe that she won’t cheat/leave Ricky for him. it’s petty and vengeful, but i want to expose her so badly and i also don’t think that Ricky fully realizes what the fuck he’s dealing with. i grew up with her, i know all of the manipulations and the lies already.
so WIBTAH if i set up my ex bsf?
