There are 5 of us in a friendship group, we've all known each other over ten years and have a lot of fun together. Occasional weekends away, meals out etc. Sometimes we'll meet up for a coffee somewhere when it's all of us, sometimes a couple of us/them will meet up etc. All good as far as I'm concerned.
One of the women messaged me yesterday to ask if I fancied a coffee at a new tea room where they have a big garden, so no issue with social distancing etc. Lovely. We went - spend two hours there and had a nice chat, I haven't seen her for months because of CoVID.
I sent a message to one of the others last night and got a reply saying she's seen my car outside the place as she was passing. I said 'yes, I met ** for a catch up, it was nice in there if you fancy it some time'. Her reply was 'well I would have fancied it today but I wasn't invited'. I thought she was joking initially but no, she's sent a message on group chat saying that she doesn't think it's kind to leave other people out and can we agree that we should all at least have an invitation to such things next time. The other women are all ??? and also initially thought she was kidding, particularly as out of all of us, she is the one most likely to arrange something without the others - which is absolutely fine - no one has an issue with that. She does like to know what everyone is up to and finds it strange if people don't tag themselves in on FB etc (something I never do).
I just can't be arsed with it. We're all in our early 50s and just find this all so ridiculous. I can't be bothered with this schoolkid stuff and neither, it seems, can the others as they've all said the same thing. One has also reminded her of when she asked her and one of the others to go on holiday and that she's going away for the weekend with one of them at Christmas (also fine) and that's gone down like a lead balloon and now she's not talking to any of us. I also don't want her to feel shit because I genuinely really like her! AIBU to think that it's perfectly fine, and normal, for friends not to do every single little thing together??
