Every single one of my female friends' partners did the traditional asking permission from the father thing. These are weddings and engagements taking place over the last 15 years, and as recently as 2023. When it has come up in conversation, every one of my friends has been shocked that my DH didn't do this as they find it an important tradition.. Fwiw, I told him that if he even dared consider discussing the matter with my dad then I wouldn't marry him. He agreed that the thought had never crossed his mind and DDad said later he would have laughed him out of the house, telling him to go and ask the right person.
Mind you - every other one of these friends had a church wedding whereas DH and I had a civil ceremony in a hotel so we obviously have a different view on tradition.
As for the other questions:
a) Did both of you have an engagement ring or neither, and if so who paid for it?
I had a ring, which we chose together. DH got a watch at the same time. We split the cost of both purchases evenly.
b) Did your dad walk you down the aisle?
Yes, which wasn't my original plan but he insisted and got quite upset. My DSis died young so it was a big deal for him to play this part at one of his daughters' weddings. We agreed though that he was "walking with me" and not "giving me away".
c) Who made speeches at your wedding? Did you? Your mum? Your MIL? Your maid of honour? Or was it mainly the men?
DH, Best Man (BiL) and Me. Dad was offered but didn't feel comfortable. Bridesmaid and Mum also offered and weren't keen.
d) Did you change your name to DHs?
Double-barreled.
e) How about your children, what name did they have?
We don't have children.
f) Did you do shared parental leave when you had said children?
As above.
