Think the problem is a lot of people go into marriage, thinking their quality of life would improve. Then become surprised and angry when their quality of life actually deteriorates. Woman blames the husband. Common line is "嫁给你生活品质反而变差了“. Start finding fault. Start to believe that the reason her quality of life deteriorated, must be because husband not doing enough. Constantly finding things for the husband to do, to try and make him contribute more. Man also blames the wife. Feels the wife expects too much and nags too much. Restricts his freedom. Constantly pushing him to work harder and harder to provide more more more. Don't give him time to rest.
End of the day, both sides should have known that quality of life for both of them is going to drop when they get married, not improve. If they went into the marriage with this understanding, they will have proper expectation and not be disappointed and become bitter and resentful.
