My two relatives were meant to come to stay. Its been planned for the last 7 months. I planned out our 3 days together to make sure there were things theyd enjoy, bought food in, found and booked a restaurant based on what they said they wanted to eat. Spent my only day off blitzing the house, prepped the guest bedroom so it was all nice. One of them has got a cold so isnt coming. Told the other one to still come and she has cancelled saying it be better to come when we can all meet up. But didnt even make a comment to say thanks for going to the effort or acknowledge how long we've had it planned or anything. AIBU to feel a bit put out? They knew id planned everything, bought food. I would have at least made a comment to say sorry I know youve planned/bought stuff. For context, the two relatives are related but not a couple and dont live together.
