I have close friend of 40+ years, our families were very close when we were growing up her mam and dad were like an auntie and uncle to me etc.
when we were about 15 her cousin was born, we loved visiting and she was even flower girl at my wedding 7 years later. In the last 20 years I have remained close to my friend but rarely see her extended family. Every couple years we might do a weekend away and her cousin (now adult) will come.
A couple of years ago at my friends 50th, cousin was talking about her wedding (recently engaged no date set) she said we (the general group not her cousin) would be invited to the evening do. Very kind of her to include us.
This year I received an invite to her hen do which is in august, sadly I can’t attend due to health issues so I declined.
i then received a invite to the evening do and typical I’m at a show that evening, it’s a one off event that we got tickets for about 18 months ago. It was something I got for my husband as a gift.
Now we could miss the event and take the financial loss or try to sell tickets (bought locally so can’t just do it on Ticketmaster) but I’d feel bad for dh as there are two other events I couldn’t attend due to my health issues so, one we resold tickets on tm the other dh took his brother. Plus dh has never met friends cousin so naturally he’s less bother for wedding.
So I messaged cousin and apologised and said we had a prior commitment, she was fine but when I spoke to my friend she was off with me. Mentioned something about how could I have double booked? But I booked this event before bride had mentioned a date or even a year. So I don’t think I did double book? Should I have given up the event?
