I never post on AIBU but I have the right hump anyway so prepared to be flamed.
My friend recently got engaged after being divorced for three years. I'm over the moon for her and wish her all the happiness.
Here is my AIBU- we did the big extravagant hen for her 6 years ago. I was involved in the organisation despite not being a bridesmaid and the whole thing while fun cost a fortune. No problem, it's a one off. Only now it isn't as she's talking about her hen again, going abroad the full works.
My situation has changed. I'm now married with two kids, we were all child free on her first hen and living in pandemic land the last thing I can get excited about is a hen trip. We were chatting on the phone and she got really upset with me for saying I might not be able to make the trip (planning for next year) she said it was like I wasn't taking her new marriage seriously (?!) that's not the case at all.
This is so massively outing but I actually don't mind if she sees it and if I get my arse handed to me I'll take it on the chin.
YABU - she's your friend and she's excited you should be excited too
YANBU - she's had her turn and should be happy with either something low key or accept not everyone will go
