Although the wife's family is also a man's family, the relationship between family members has a scale. It is human nature to support each other in life since ancient times. However, there is a premise that those who help are willing to help and those who are helped should be grateful. As the saying goes, helping is human, not helping is duty. Therefore, helping relatives is not an obligation, not a responsibility, but a human favor.
However, in the real world, there are many experiences like this man. Influenced by feudal ideas, parents in many families have a serious preference for sons. They not only prefer their daughters, but even ask their daughters to help their sons. Even after her daughter got married, she still didn't stop asking. Among these parents' values, the daughter was born to help her son, so she took her daughter's contribution for granted.
Just like this man's mother-in-law, she thinks that what a daughter has should be taken for granted but unconditionally shared with her son, and what a son-in-law has is her daughter's. Therefore, the mother-in-law doesn't think she is asking too much, but thinks that they should give generously to help her son. However, for the sake of his son, he personally broke up his daughter's family and ruined her marriage and life. What is more exasperating is that a man's wife is as confused as his parents. She lost her small home because of her parents. If she doesn't wake up in the future, she will suffer more harm from her parents.
