Based on my own - very Eurocentric - experience, and my circle of friends, relationships where only one part is the provider all failed (to reiterate: not all of them fail, just the relationship of people I personally know/friends of friends). It was about the money. Once one party starts to feel that the other is spending “their” money, the wheels come off. Maybe it worked better when divorce was frowned upon.
As for the protector… it does not matter how buff you are, in 99% of the time your average male will still be more able to fight off a physical threat. But yes, there are men who feel inferior because of being less fit. And there are men, who will applaud it and have no trouble lifting less weight than you. Guess who is more self confident…
About the procreation: that one I could imagine. If you want to badly have kids as a man, or want to badly leave that option for the future, you’d probably pick a spouse with enough “runway”. But there are also many guys who rather enjoy the money and don’t want kids.
