I'm of a generation and demographic where taking your husband's name was exciting and girls would practice their new signature with new boyfriends 🤣
I don't think I'd do it now, that said, I do/did like having the same name as my DH and DC so I'm not sure what the solution would have been.
So DH is long deceased and I still go by Mrs DH. It's been my name for many decades now and is the name I share with adult DC.
Life has moved on and I have a new DP, who I will never marry, but sometimes it does feel odd to be referred to as Mrs, especially in his company.
I know people will say no one uses titles, but when you're aware of it (and maybe when you're older?) you'd be surprised how often it comes up.
