The core of managing a marriage is to be a person who is needed. When you invest more time and energy into enhancing your own value, and when you become a high-value person in the eyes of your partner, they will realize that if they do something to hurt you or leave you, it is a loss for them. In fact, they will not choose to leave you. The essence of love is need; those who only talk about love and live for love often lack maturity in their thinking. If your partner abandons you, ignores you, or no longer cherishes your love, the core issue lies in their inability to gain satisfaction from you. Therefore, they may seek others who can fulfill their needs to replace you. This is the essence of managing a marriage. Each of us must learn to accommodate each other within the relationship, not to constrain one another, and to transform ourselves into someone who is always needed in order to be happy together until old age.
