I asked my DP what he wanted to do on the day. His DD is 21 but doesn't really get on with her mother (his ex) so he planned to spend the day with his DD and I with with my children who are late teens and he'd come over later.
I'd had a problem with my DP coming round later and later and cutting weekends short but after a talk it has been sorted. I hadn't asked him what time he was coming round christmas day but he arrived at 7pm which was fine we'd last seen each other on the Sat.
He really is lovely kind and thoughtful. It turned out his DD didn't spend much of Christmas with him and announced to him she was going to her cousins for dinner at around 1pm.So my DP didn't have any of the Christmas dinner, he'd bought and spent the day alone and went for a run. I felt hurt that he didn't feel he could let me know and come round earlier. I thought his DD was quite rude to change her mind on the day. I just find it all a little odd.
