You've thought out and presented your view well but I don't agree with this. Just because a 60-year happy marriage is becoming a rarity does not mean marriage as an institution has been eroded by the winds of evolution. It simply means it is more rare. And, many would say, therefore more valuable.

Marriage may change over time in the face of the problems of its day, but it will still remain.
As one example of the value of stable marriages, just look at the average differences in outcomes between males raised without a father, and males raised by a father and mother.
Quite certainly, in any individual case, you may have even contradictory results. But overall, on average, the children of intact and traditional homes outperform other children when it comes to things like avoidance of jail, academic achievement, lifetime earnings, etc.
These differences add up over time. And overall, those who are products of intact homes gather and control more resources than the products of less traditional approaches. As a result, the relative reproductive fitness of the first group is enhanced.
Now, the details of marriage and expectations will change in response to social conditions. Dowries are no longer common in this part of the world, for example. So marriage changed, but it still persisted.
So I'm not arguing at all that it will disappear -- only that its details will change but it will still survive.
