DH and I have been married for 5 years. He has two children, aged 16 and 19. He was divorced when we met. We have no children of our own.
Since his divorce, he and his ex wife worked it so that the children spent Christmas with one parent and new year with the other, reversing each year (so each parent got them for Christmas Day every other year).
Last year was 'our' year for Christmas. Stepchildren decided to stay until Christmas Day lunchtime, then go to their mum's house for Christmas dinner. Fine by us; they are old enough to decide for themselves.
This year, like last year, we're hosting Christmas for my family. We have 4 bedrooms, including ours. Because the stepchildren were staying last Christmas Eve, I put up my family, at my sole expense (i.e. not jointly with DH) at a local hotel, but unsurprisingly they prefer staying at our house.
DH and I agreed a couple of months ago that we'd host Christmas for my family again, and I assumed that since it wasn't our year for the stepchildren, we could accommodate the family in our house. However, he's announced that the stepchildren want to do the same as last year, and stay in 'their' rooms, meaning that my family have to stay in the hotel again on Christmas Eve, which they don't really want to do and nor do I, really. It feels inhospitable.
I'm annoyed with DH; I think he should have consulted me before changing the long-standing alternating Christmas agreement. He says that it's changed whether I like it or not, that he isn't going to tell his kids that they are unwelcome and that my family should effectively suck it up. AIBU for being annoyed?
DSD is at university far away, so we don't see that much of her. DSS is with us every 2/3 weekends. In my view they don't live with us so it seems a bit much for them to have prior claim on 'their' rooms at the expense of any other guests.
DH's ex wife lives 20 miles away. DSD drives. I don't see why they couldn't drive over on Christmas morning. My family live 100 miles away, and I have a very young (under 5) niece and nephew; I don't think it's fair to suggest that tinies are driven a long way on Christmas morning.
Am I being unreasonable?
