AITA for refusing to lie about why i stopped inviting my friend to group plans?

I 30F have a friend Nina 29F who i met through work years ago. She is fun one on one, smart, sarcastic, and honestly very charming. The issue is how she acts in group settings. She constantly corrects people, turns every topic into a debate, and has this habit of doing little jokes that land more mean than funny. Like pointing out someones typo out loud or mocking a story while laughing so it sounds playful but isnt.

Over time our friend group started avoiding plans if Nina was coming. People would suddenly be busy or suggest smaller hangouts. I didnt say anything to her because i hate confrontation and hoped she would notice on her own. Eventually i just stopped inviting her when i hosted things.

Last week she asked me directly why she never hears about group plans anymore. I panicked and said schedules just havent lined up. She didnt buy it and pushed harder, saying she feels iced out and wants honesty. I tried to dodge again but she straight up said please dont lie to me.

So i told her. I said some people feel uncomfortable in group settings because of how she jokes and corrects others, and it changes the vibe. I told her i didnt want to hurt her feelings but i also didnt want to keep lying. She got very quiet and then very angry. She said i should have defended her instead of excluding her, and that real friends dont talk about you behind your back.

Now she has told a couple people that i betrayed her and embarrassed her. Some friends say i should have kept making excuses and spared her feelings. Others say she asked and i answered honestly. I feel awful but also weirdly relieved i stopped pretending.

AITA for finally telling her the real reason even though it basically blew up the friendship?
