I guess this isn't so much of an AIBU as a Wwyd.
We've been invited to my cousin' wedding. It's the Saturday at the end of half term. It will involve 2 nights stay (travel up on Friday, wedding Saturday, travel home Sunday. He has lived quite a distance away since a child (making regular visits with his parents "home". His mother is my godmother. I've verbally said we will be able to go.
Told Dd about it today & she doesn't want to go. I understand why as it's in the middle of her GCSE's. I'd thought one weekend would be ok. I could go alone (with my parents) & dh stay home but then I know Ds will not want to go as he hates anything that will take him away from his Xbox & his theatre group & he's not good at formal occasions (asd).
If we don't go it would he seen as quite a big snub.
Is Dd being unreasonable or not?
