I assume dh’s daughter struggles with idea that another perosnal, who maybe she doesn’t know well , views dh as dad.
its a complex thing.
my SIL and brother are devout Christian’s. They called each others parents universally as mum and dad. I’ve had a couple of periods in last 36 years when I got profoundly irritated by my SIL calling my dad “dad”…mainly becuase my dad wasn’t always a nice person to me,in fact was a pretty lousy parent in many ways. Not his fault in some ways- I think he was neurodivergent…but he died last year at age 87 so not of generation to find that out. But dad was always on best behaviour with SIL, she only knew one side of him. There was stuff she’d say to him thst id never have been allowed to say even as a 50 year old women. 🤷♀️😳
but I love my SIL, she means no harm ..just a bit naive and guileless 🙄. So I kept my mouth shut . Talked to myself to ignore it. Both my parent dead now so don’t have those weird feelings now when she refers to them.
but it sure did wind me up at times . Perhaps becuase I was an only daughter, maybe with my 2 elder brothers it didn’t impact them as much.
I don’t think it was jealously as such, more an irritation of her intimacy with him based on rose tinted spectacles, and not the warts and all I experienced.
so, it could be a lot of complex things going on. His daughter presumably missed out on some of intimacy your daughter had? Don’t right it off as simple jealously…Sd experienced a different dad potentially.
still a bummer…but tread carefully…turn on full empathy and try to talk to her about why she feels this way. Dig into whys in non challenging way..or get dh to do this…even if it doesn’t change wedding outcome it could just help to improve relationships between you all longer term.
as other said, you’re her biological and legal parent, you give her away. One up for female equality…do the mother of bride speach too…and tell your daughter to keep her own name ! 🤣🤣
