Something similar is happening in Quebec, Canada. Avoiding marriages and living in common-law partnerships (usually monogamous) seems to be a popular trend with the younger generation.

(Speaking for myself, he is the only Republican I ever wished to win a presidential campaign.) Maybe from this Wahsington Post piece? Was it, really? Or is it just a projection of the current state of affairs back in time to a period for which we lack evidence... I don't know, haven't read much about it, was just wondering...
