I don't know where you live but the "woman as homekeeper" thing is the norm in most Western societies too. Women have, of course, worked throughout history but, culturally, it's been more the norm so far that women have taken housemaker and child raising roles. My mom left her job when she met my father and she has never been employed since. The same applies for about half, I'd say, of my friends' family situations.

It is not unrealistic or old fashioned for people who agree on their roles to settle into those roles. There is nothing wrong with anyone looking for someone who complements them as long as the intentions are good. Indeed, finding someone who doesn't complement you is more likely to result in disastrous relations.
