Bear with me, this may be complicated.
We are a very small family. There is DD, DS and I. DD and DS have partners. We live in 3 separate small houses.
The arrangement this Christmas was for DD and I to go to DS's house for Christmas Day with DS and his partner. DD's partner is working Christmas Day but DD and her partner will go to his parents house on Boxing Day.
DS and his partner were going to his partner's parents on Boxing Day.
There was a possibility that DS may have to work on Christmas Day and today he confirmed that was the case. We had agreed that if that happened we would move our family meal to Boxing Day.
DS's partner will go to their parent's house for Christmas Day, which is fine. However DS today announced that our family meal at his house on Boxing Day will now include his partner's parents. Meaning there will be 6 of us. That sounds OK but really isn't, as DS's house is very small. The kitchen table seats 4 at a a squeeze and the living room only seats 4 people on a sofa and one armchair. It will be a nightmare especially as 3 of us are disabled.
So AIBU to want some time for just our immediate family to relax, exchange gifts and have a meal together on one day over Christmas? DD has suggested that she and I have Christmas Day at my house but I would really like to see DS as well. I have gifts for him and his partner and was really looking forward to it.
DD and I don't really know DS's partner's parents, have only met them once.
