I do, but only the fantasy idea of a happy family. The reality would be different of course - there are reasons why dh is estranged from his parents and brother.
I get angry for ds as he has a set of grandparents who have never seen him and I worry that in the future ds might blame his dad for this somehow.
Ds being born has meant that dh has got back in contact with his extended family though. We see his aunts and uncles, cousins and his gran fairly regularly and they remember ds at birthdays & christmas so at least he's got some of that side of the family in his life.
Strange things I miss. I don't get the stories about dh when he was a little boy, well a little from other family. I don't know little things like what dh weighed when he was born, what childhood illnesses he had (he says he can't remember), when he first walked/talked. Stuff like that.
Then there's wider family stuff. There's going to be a wedding this summer and it'll either be mil/fil or us who are invited. I suspect we'll not be because that will cause less trouble (we'll not take offence) but again, I'm sad for ds missing that and I'd like to see dh's cousin married.
Dh's gran is very old and dh won't be able to go to her funeral (again, not wanting to cause trouble). I think he'll find that very hard. I also worry about the mental fall-out for him when his parents die and it's too late.
But mostly I just like that we don't have to do the year about thing for Christmas.
