Bill not weird IMO, as DH was doing just as much work as me at home, as well as working full-time/earning all the money.
Whether to go with a matriarchal surname line or a patriarchal surname line is a choice to make and one could argue for matriarchal but, as the UK has always been patriarchal, (as far as I know), and both our families were following this naming method in the past, I was happy to go that route.
Giving children their father's name is not a bad system, as you can't really have it both ways, unless girls get their mum's surname and boys get their dad's? But I can see that in future with so many blended families, using the mother's name might be more logical/ consistent. (As long as she keeps her name the same all her life!)
I knew that I wanted to keep my name when we got married as it was MINE, and DH understood/agreed. (Phew as I wouldn't have wanted to drop my name.)
But for the kids, it seemed like a nice gesture to want to give them his name, especially as he was financially looking after us all and therefore had a lot of responsibility.
Really hope the OP manages to sort all this surname business out with her fiancé well before the wedding, as might well turn out to be a deal breaker?
Seems like a small matter initially, but in fact surname is rather important as often ties in with our ideas of identity and self-worth I think?
