A close friend "M" stopped being my friend about 6 years ago. It was the usual pattern I often read about here - cancelling things, not replying to messages etc. This habit of messing me around went on for about 2 years before I gave up and stopped initiating everything, then contact stopped.
We were both part of a larger group going back 20 years and M stopped going to group social events around the same time as she started cutting me off. Obviously others were surprised but they weren't her close friend. We would often arrive to these group events together and we were always in touch independently meeting just the two of us or with another friend. What upset me most around that time was she stayed in contact with 2 of the group: 1 is in another city where their partners are also friends and they do weekends away together, so thats a little different. The other is also my friend and we would often meet as a trio, thats the thing that really hurt, why she was the chosen one and I was not. It felt very callous and personal and despite many attempts I never found out why she stopped contact.
Due to restrictions in geography and family, our 'old gang' have very structured meet ups with our children including an annual Christmas get together and an annual weekend away, same dates every year. Sometimes someone hosts a party or BBQ outside of this. These are usually arranged via a WhatApp group which is not used for chat, just confirming arrangments so M is still lurking on these groups from years ago. A few months ago out of no where she turned up at an event, I knew from the group that she was going and was gobsmacked. I was a nervous wreck and she just acted like I was an old acquaintance asking me about my family etc. Apparently beforehand she messaged some of the group saying how she was looking forward to seeing them and so sorry it had been so long etc, but she never messaged me and again, it felt very personal. I thought i might be ok to see her but I was really on edge and had an awful night. It brought back how upset I was literally for years over it, how it made me question myself and my relationships with people and knocked confidence out of me for so so long.
I've been invited to a house party by one of the gang in another city in a few weeks. I'm travelling a few hours and am bringing the kids to a family member in the same city and staying in a hotel, its a big deal to organise and I was really looking forward to seeing everyone. I just saw a msg on the group chat from M confirming she is going. Suddenly I don't want to go and I feel like she is ruining everything. I don't have a huge circle of friends and these 2 or 3 times a year events are the big things in my calendar. I guess I can't do anything about it but I'm a ball of stress now. I just can't face her. DH thinks I'm being silly for giving her the time of day but I can't help it, I feel really angry with what she put me through. Its like she woke up one day and decided she wants her old pals back and doesn't think there are any repercussions
AIBU to be so upset about this? Would I be cutting off my nose to spite my face to avoid these events? I have restrained myself from bitching about her in the past, should I be telling everyone how I feel about her or just biting my lip?
