DH, his sibling, me and my parent always (20+ years) spend Christmas Eve at his parents. That's our main Christmas celebration (we're not from UK). This year his mum is very ill, suffering from some strong medicine side effects and can't host. We offered to cook dinner and bring it to them, but she declined.
DH has said prior he would just pop by to say hello and give them our presents, then come home so we would have dinner.
Then the day before he announces he is going to his parents as they invited him and his brother to celebrate together at 7pm, apologising not to have invited others and hoping we'd understand. I was a bit upset by the last minute change as I was expecting my DH to visit them earlier in the day, leaving us enough time to have our Christmas dinner. I said to DH that we agreed we'd compromise that way, to which he got defensive and argued the compromise here is that he goes only for two hours instead of the whole evening.
In the end we ate our dinner at 10pm. Who was BU with Christmas expectations?
