Interesting data at that link.
As i was reading thought the thread, and saw someone mention that “even marriages from the 70s ended up in divorce” I was thinking how the sexual revolution peaked in the 70s, so that is not at all surprising.
the data you linked supports that conclusion.
This story has to be the absolute infinitesimally rare case from that era of relationships. I don't regret at all how it turned out. I certainly don't recommend it to anyone either. It doesn't exactly jibe with my Christian beliefs or practices. I can only guess that in some way I don't understand, my wife and I have been blessed.
