I guess it's different in the States because the civil and church ceremony can happen simultaneously, during the Mass, which conflates the two things. They're two separate ceremonies here, and the Church wedding is the higher one and that's one per customer.

But even civil marriages here have a lower remarriage rate. Americans basically want to change sexual partners and get approval for each relationship, to kinda play it off, whereas everyone else is more honest with themselves that they don't have 2 husbands, they have 1 husband and 1 boyfriend.

It's adultery, either way, but the second way you can at least easily dump the boyfriend and be back in good graces with the Church, or wait to marry him until after your husband dies, and you avoid the scandal of appearing at the altar dressed in white over and over and over, while you have other husbands wandering around the town. 🤪
