Our grandmothers and great-grandmothers were super women. They set high standards for themselves, and men were complimented by their attention. They often received several offers of marriage and could choose the most worthy of them. Because this man would be their partner for life and the father of her children, they were careful to weigh character as well as material considerations. These marriages lasted and were blessed.
Where did we go so wrong?
Women died in childbirth in your scenario, too—men might have several wives in a lifetime —and consider that a life expectancy of 45 did make for happier marriages.
I love these stories for the romance of them. Call me old-fashion, but that is the way love and marriage should be.
