A friend is having a party to mark a milestone event. A gathering of about 20 - 25. I found out that a group of people are going that I make a big effort to avoid since I found out they spread nasty gossip about me a few months ago and were generally not very nice (I had done nothing to provoke this and was just living my life which they seemed to take excessive interest in). She is friendly with them as she has more in common but I've always felt like an outsider with that group so prefer to just avoid them rather than try to fit in like I used to when I was a bit younger and naive about them.
I explained to my friend that I didn' t feel comfortable going if they are all there, I'll feel outnumbered and exposed and whilst in the past I would have gone just to please her, I no longer want to do things I'm not comfortable with or go to social events where I know I wont enjoy myself.
I offered to do something else with her to mark the milestone like take her for a meal but she's not having it. She actually said 'you can't do this to me' and called me weak minded for letting these people get to me. I was just being honest but feel like its backfired and she'd rather I just shut up about it and attend regardless of this situation.
AIBU to not attend this social event?
