Your dad.
i mean all this came down to you like im sure ur fiance would have asked him if YOU said you wanted him to follow that custom
How would you explain it people who don’t understand where I’m coming from.
Personally I don’t think you should even have to. Your dad doesn’t own you and your decisions, you’re your own person.
Also my dad is very traditional and I don’t think he’d care. He’d be too busy congratulating me on my engagement and being happy for me
