LOL that probably was truly only to the Mid-90's at best.
Nowdays, even if it's still practiced in some countries it's seen as a sign of sexism that is generally dissaproved by the community xD
Marriage is still used but is more like a way to sum your efforts with those of your couple to stablish a solid patrimony for both and their children (if any xD) as also to give mutual emotional solace and support xD (things are a bit harder in modern times than it were back in the 80's economically speaking xDU).
Marriage is more of social instrument designed to maintain sustainable birth rate in a society by freeing up the women from physical work so they can concentrate on giving birth and keeping their progeny alive through the early years. You may guess that I don't consider childbearing and little children in general particularly cute.
