It is said that true love in marriage is when two conscientious people mutually reciprocate kindness. Because love's giving is fundamentally not about demanding or exchanging. So you will find that the vast majority of marriages in China are not actually about love, but more like a partnership, formed to continue the family line, satisfy sexual needs, or achieve a leap in quality of life (or avoid decline). Since it is a partnership, it should operate according to the logic of cooperation: one side provides conditions, the other offers corresponding costs, both feel it's worthwhile, the cooperation is established, and each gets what they need. But the problem is, people often inject emotional expectations into such relationships. Once one party begins to feel it's not worthwhile—whether expressed as disdain, indifference, or renegotiating "conditions"—it essentially means the balance of this cooperation has been broken. And when the moment comes that "the price needs to be renegotiated," it actually signifies that this relationship has reached its end.
