Long story short, I am in a group of 5 friends. Friend 1 lays into me one day, via group chat because we share differing political views. It came from nowhere, we had not been discussing anything. I think friend 1 may have been drunk?! I was on holiday at the time but opened my tablet to a very nasty barage of abuse sent to the group chat with friend 1 saying they wanted nothing more to do with me and then leaving the group. A couple of members reacted with WTF etc after friend 1 had left and agreed it was out of order and uncalled for, everyone else said nothing. Friend 1 met up with friend 2 a few days later (they live v closeby) and friend 1 was re added to the group. Friend 3 is arranging a meal for the group and all are invited. I am hesitant to go as Friend 1 will be there, so I told friend 3 I'd need to think. Friend 3 says they understand if I don't want to come and we can arrange something else soon but it would be a shame that I need to miss out when I haven't done anything wrong.
What is the protocol here?
I don't want to ask people to choose sides and split a group of old friends but I don't really want to spend any time with Friend 1. If I refuse to go where Friend 1 goes, I will effectively cut myself off from the group unless its something I arrange myself or one on one with other members.
AIBU - should I just go?!
If I do go, should I confront friend 1? I will never be friends with them again so I don't really care for trying to hash it out and make amends but I also don't want to sit pretending to be friends.
Wwyd?
