As far as I'm aware, there are no rules for this in BrE and culture doesn't come into it.
It's just as acceptable to have the female as the subject as it is the male, so there's no problem with.........
She married him.
He was married to her.
He and she are married.
She and he are married.
We also refer to marriage as............
tying the knot
being joined in Holy Matrimony
I'm sure there's many more, but I can't think of any at the moment.
