I have a DD. She's 11. Her dad has a new partner whose son is 17. He's a great boy, he's brilliant with DD and an all round lovely chap.
So, DD is with her dad for Christmas Day. They are having a family dinner. She will come to me at 8pm-ish. They have been talking about Christmas. They are all going to visit my ex's family on Boxing Day. Stepson doesn't want to go.
So DD told him he could come here.
I don't have a problem with him here on Boxing Day or coming down on Christmas night and staying over. Is it weird to have him here?
