We are three best friends.
Friend A, friend B and myself.
Add into the mix a third woman, let's call her "Chanel".
Myself and friend B are very chilled. Friend A can be quite prickly.
Chanel has a very close relationship with Friend B. Chanel has done a lot to help friend B out in her life - even looking after her DC when she had no money for childcare. But Chanel did something not nice at all to Friend A, so Friend A hates her.
I have always stayed like Switzerland on the issue.
However, I moved overseas, so no longer live near frind A or friend B (bit lonely!) and Chanel sent me a message to invite me for lunch.
I have agreed to go, and Friend A is now not speaking to me since I told her I was ging.
Friend B is still very close with Chanel, but apparently I am not allowed to have lunch with her so seems a double standard.
We are 40 by the way, although I know this sounds like it would happen to 12 year olds.
I honestly can't imagine a situation where I would even care about any of my friends having lunch with anyone given all the real problems to deal with in the world, so I have just left her to it - but I do feel some guilt also because I know Chanel hurt friend A very much.
AIBU to think friend A is being childish here? Or am I actually disloyal for having lunch with her?
