I honestly don't know if IABU or not.
FIL will be 70 this weekend and MIL has arranged a family lunch. Originally it was going to be near where they stay, near their other invited guests too, but 20miles from us. That was great, I was going to drive, all happy.
However, MIL called DH earlier to say they had booked Xhotel near us instead as everyone fancied it so she has just said to them all 'we can go back to the wild family home for tea/cake/wine afterwards'.
I had not planned for this at all but I now seem to have 8 guests coming! AIBU to feel a bit put upon?
