I have a friends wedding coming up in a couple of weeks. It's during the week and is an afternoon and into the evening do.
DH is not coming, he is in work anyway but he's not a big wedding fan (and doesn't know friend well anyway).
It just so happens that the wedding falls on DHs birthday.
He asked me if I'd be gone all day, I said yes I likely won't be back until late on.
He seems to think I should leave early because it's his birthday whereas I think a birthday happens every year, a wedding only once (hopefully!).
It's not a big birthday (I.e. 40th). He doesn't even usually do anything extravagant for his birthdays and he will be in work during the day anyway.
He doesn't have family living here which I do appreciate but he will have DC (his) with him so not alone and I have said we should do something the weekend of his birthday week too.
Who is being unreasonable?
YANBU - you should stay at the wedding for as long as normal / go with the flow on the day, DH is a grown up and doesn't need you there on his birthday.
YABU - stop being tight, leave your friends wedding early to do something for DHs birthday.
