I (22 F) quit my job at a company that I worked at with my best friend (21 F) because of how she treated me inside of work.

Me and my friend are part of a trio (Me, 22F, and 21F)and I have know them both for just under 10 year. My youngest friend (Let's call her P) got me a job at the company she works at over a year ago.

She was fine for the first 3 weeks but after that would start creating beef with me out of nowhere and would then start to take the beef outside of work, she would have a go at me for the fact I'll need to be told something more than once (she's known this about me since we became friends) P would argue with me over the fact that I helped another colleague with their work or entered her office to grab something whilst she was in there (alone and not working on anything important)

P has also purposefully messed up my meeting with a BOD by consistently tapping her watch 20 minutes before the end of the timeslot and sitting at her seat huffing and crossing her arms anytime i said anything because I looked at my watch in one of her meetings (That had run over by an hour)

It got to the point I wouldn't hang out with her outside of work because she would just bring up things that happened in work. She was no fun to be around anymore because it felt like P was belittling me every chance she got, she had used insanely harsh words and kept calling me names like a child.

She then involved our other friend and accused us of hanging out without her (which we didnt) and planning things without her (knowing that she is shit at planning and will 99% of the time back out of our plans as a trio anyway)

Now, I have quit the job and moved onto something else, purposefully 'losing' contact with her as I did it. She is still implying that everything is my fault and keeps trying to repair the relationship that she broke.

I'm happier without her, this is definitely a warning for working with friends but seriously, AITA in this situation??
