Let me provide some context:

I (have been friends with a girl we'll call Leah since childhood. She was my best friend for years, and also part of my main friend group, working as some sort of pillar.

Now the thing is, she's a horrible person. Manipulativs kind of horrible, textbook narcissstic kind of horrible, main reason for fall-outs kind of horrible.

In november 2024, I had a huge fight with her. I tried to keep it between us, but she made it escalate to a group issue, and made them take sides.

Eventually we all made up and things got better. I still had the same thoughts about her, but kept it quiet and just sucked up my anger towards her to avoid drama.

But my last straw was when Leah had a fight with my friend Grace, bc Leah was talking shit about Grace to Grace's boyfriend.

Grace also had a fight with her boyfriend bc of this, and told her about my and her desicion to quietly stop talking to Leah due to all the harm she was causing us in the past AND present, and he went to Leah to tattle about it.

Now Leah says I'm an asshole for getting in fights that are not mine and picking sides (Which I didn't exactly do, I stopped talking to her due to a tom other reasons, her fight with my friend was just what made me realize it wasn't all in my head.) and leaving her without saying a word. AITA?
