My response was merely, "not in every case."

Then without the sex, these women are just best friends. There's no procreation involved to bring them together as one, so the only bond they have is companionship. That's not what marriage is all about.It's so much more than just living together.
IF they were young and one didn't provide the carpet munch, do you think the other would have stayed, or would she have found another to fill that need, because that's the only type of union these people can have. Kinky Sex. It doesn't go any further than that. The union ends there.

I don't know for a fact whether, at a younger age, they would have stayed together, sex or no sex. (That would be an unusual degree of loyalty these days, for straight couples, too. A fair number of straight people have told me they couldn't do Natural Family Planning because their marriage couldn't tolerate even a little bit of abstinence.)

It seems to depend on the persons involved, which is why I am wary of generalizations unless there's some kind of legitimate longitudinal study. And even that tends to be iffy, since a self-selected survey pool doing retrospective self-reporting is the least reliable type of survey.
