That describes my marriage of 23 years to a T. Unfortunately the wedding happened 27 years ago. He was gay. There are no guarantees.
Actually though, this is nothing new at all. I'd venture to say that the majority of marriages have been like this, with one modification. That is, equal distribution of labor or close to it: there was a reason in past times that men and women had different work and that's because men's work didn't allow for the opportunity to watch children while they did it--can you imagine a small child toddling around a blacksmith's forge? Other than that though, men and women rarely had the luxury to marry for love--that was an idea that was started in the middle ages with the very wealthy and didn't actually become a reality for most people until the 20th century and people started watching movies and wanting what they saw on the silver screen. Also the majority of people had a disposable income for the first time in history.
