NC because other posts could be outing
This is a long story and I will apologise now.
A while back there was a group of 5 of us as friends 2 moved away and then there was 3 of us we will call the 2 people I am referring to as Marie and ava.
We all got on so well and had lunches out and days out all pre covid was 2019 then Marie and ava fell out a big fall out, which then put me in the middle. I told them both from the start I would not take sides and if 1 invited me somewhere and I made plans I would not cancel them because the other did not like it or the other say tried to make me a better offer in term of plans. I tried to keep it as fair as possible.
Marie grew a strong hatred for ava and even when ava tried to get back in to Marie's good books she was adamant she didn't want anything more to do with her. This was because once they fell out things started to surface that ava had said about Marie or lied about and Marie couldn't forgive that. Which is her choice and I wasn't about to play mediator for the 2 of them and get dragged into something that didn't directly concern me. A couple of month after Marie and ava fell out, Marie had a garden party for her family members birthday which I was invited to, ava got wind of this and then asked me to do something with her that same day, I declined and said I had already been invited to Marie's and accepted so would be wrong of me to either tell Marie that I was now doing something with ava instead or to be devious and do something with ava and not tell Marie the truth and make an excuse as to why I was not attending anymore (the latter is what ava suggested I do).
This caused a huge fall out between me and ava because she said she had known me longer so favour her over Marie and it was unfair she was being left out, I explained that her and Marie had fell out so that's why the invitation was not extended to her and that I had told her right at the very start I would not cancel plans with one or the other just because that's what they wanted, Marie always respected this she may not have liked it when I was with ava but she never voiced it but ava always thought she had more priority because she had known me longer.
Fast forward a couple of months ever since the fall out avas family stopped speaking to me in the street if I said hello they would ignore me and walk past but they would still talk to Marie.
I asked ava even though we were fallen out at this point why this was and she said because it was all my fault that I should of favoured her and that I was the only friend she had at the time and I had caused all of this. I asked how I caused all of this because when ava and Marie fell out I wasn't even in the country I was on holiday with my family but she could not answer me. They fell out over avas kids bullying one of Marie's kids and after repeatedly telling ava Marie blew up. So again this didn't directly involve me but she still blames me.
I have had another person ava now speaks to come to me today and tell me that ava tells everyone that I am the bad one and Marie isn't because I cancelled plans with ava to go to Marie's which isn't the truth and I still have the text messages to prove it which I did show the person asking.
AIBU to go and call ava out on this?? It was a year ago and I feel she still shouldn't be dwelling on something I never done I think it's got to me because she is telling people lies about me and tell me if I am very wrong but I actually fail to see what I did do wrong, I am happy for it to be pointed out if anyone can see what I did wrong.
Thanks for taking the time to read all of this
