How about a woman with a serious mentality?

Such a woman is not easy to satisfy, because there will always be better people than her man in this world, but it seems a bit serious for the afterlife of family life. She's probably just paying lip service. As a husband, you can do your own thing. Don't argue with her. If two people want to live a good life, they always need mutual understanding and tolerance. Besides, no one is perfect. More tolerance!
