I don't mean private in the sense that we shouldn't discuss them, I mean private in the sense that the actual details of the relationship occur in private and that we don't know them. It is very hard to judge a relationship from the outside because a lot of what goes on in a relationship is private: private conversations and communication, the way a person expresses love or likes to be shown that they are loved, the way romantic conflicts are handled, what initially attracted a couple to each other, minor quirks and eccentricities, pet peeves, sexual compatibility, changes in personality and values, and so on. I don't think we really know most of these things about Elon Musk's marriage, and I would be hesitant to draw broad conclusions without them.
