I lived in a flatshare with three friends. I did something a year ago which upset two of them. Granted, it was a huge mistake on my part, and I tried to rectify the situation without success. A month ago they suggested it would be better if I found somewhere else to live because our friendship has broken down due to my mistake. I agreed and moved out.
I have another friend, let's call her Amy. Me and Amy were very close. However she has chosen to move into my old flat with my previous three friends. I feel like this is a huge betrayal and I no longer feel welcome in that flat. I know I caused the mistake originally but I would have expected Amy to be loyal to me and not move in with the people who kicked me out. I have expressed this to Amy and she says she had a right to move into my old room because she was getting away from an unsafe living situation.
Amy and I have another friend, Meg, who is flying over from Aus to spend Christmas and NYE with all of us. I have made it clear that I am happy to spend time in a group with Amy and be civil, but I do not want to spend NYE with her. I am hurt by what she has done and I have made it clear that I want to spend NYE with Meg. Amy is obviously not happy with this and thinks we should bury the hatchet for Meg's sake and all spend NYE together, but I can't get over the fact that I feel so betrayed.
AIBU to refuse to spend NYE with Amy and insist that she takes a step back so me and Meg can spend NYE together?
