DH is upset that Daughter want to take her wife's name in same same marriage.

[Netcurtainnelly]

DD is planning on getting married to her wife later on the year.
DD has said she plans to take her wife's surname.

DH is upset that she hasn't kept her own name or gone double barrelled.

He hasn't said anything though just to me.

What do other people do who have same sex weddings re names.
Is DH being unreasonable for being upset and not understanding why daughters chosen to take her wife's name?

If it's any help our DD is fem and her partner is not, does this have anything to do with it?
What would you think?
What do other people do?
I don't really know anyone in this situation.
Yes we do get on with dd wife to be before anyone asks.

This.

Did you take his name?

Yes he is being unreasonable in not understanding why she has decided to take her wife’s name. He could just ask her and accept whatever her reason is.
Also, how is it “any help that she is fem”?

Of COURSE he is not being unreasonable to have actual feelings and opinions and it would be completely stupid to claim otherwise, even if you or others disagree with him.

What do you mean what would other people do? Leave him alone to have his own opinions would be the main thing I would do.

If you thought he might say something you would still be unreasonable to butt in, unless he has a history of bullying your daughter or something. They can just discuss themselves, as adults, and you can keep out of it.

But you said he won't say anything - so you are literally looking for support to tell your husband he is not allowed to think or believe anything that you don't approve of.

You are being MASSIVELY unreasonable.
