We have a core group of 5 couples (us included) that we socialise with pretty often. 4 have children, one does not (cnbc).
We try and do a mixture of things with the kids and as adults only, though we do do more things with the kids. They're all aged between 6mo and 7 years so still very young families. We're all expats so none of us have family close by and having to shell out for a sitter too often gets expensive. Two of us also have very small babies - >1 so it's not so easy to leave them with someone else.
Our friend who doesn't have children - let's call her Jane - keeps inviting us all to things that most or all of us can't reasonably attend - either vv last minute things (e.g - text asking us all over for dinner tomorrow night at 8pm - past the kids bed time and usually too late to organize a sitter), or trying to organize a day gin tasting on a Saturday/ adults only weekend away etc that's just not really feasible. There have been loads of others too - and so usually some/ most/ all of us end up having to decline. As opposed to days out or dinners the kids can come to which we all usually go along to (Jane and her DH included). We do occasionally organize an adults only thing but this is usually weeks in advance rather than with days or sometimes even hours notice!
It's getting to the point now where she'll message the group once or twice a week suggesting something, mainly at very short notice, and we all have to say - again - that we can't go. Then she starts getting annoyed and telling us we're all boring! She has other friends who she goes out with a lot so it's not like by us not going, she doesn't get to go out.
AIBU to be annoyed that she keeps suggesting things she knows we probably can't do?! I've long since moved past the 'oh Jane's trying to organize another lovely thing for us all to do, isn't she nice' way of thinking and now I just feel like replying to each one something along the lines of 'ffs, Jane. You know we can't do that.🙄'
YABU - give Jane a break. At least she's trying.
YANBU - she knows you all have young families and you can't drop everything at a moment's notice to go to a cocktail making class/ spa weekend away/ dinner at a fancy new restaurant. No matter how much you might want to 😂
