1. Shift in focus of life: After marriage, men often need to devote more energy to family responsibilities, such as working to earn money, supporting the family, and handling household chores. These new responsibilities may lead to a decrease in their emotional attention and investment in their partner, making them feel indifferent.
2. The gap between expectations and reality: Before marriage, both parties may have romantic and ideal expectations for their marital life. However, the triviality and monotony of married life may disappoint some men, and this psychological gap may translate into a cold attitude towards marital relationships.
3. Lack of communication or changes in communication methods: The communication methods and frequency in marriage may change over time. If both parties fail to adjust their communication strategies in a timely manner or reduce effective communication due to work, life pressure, and other reasons, it may lead to misunderstandings and estrangement, making the partner feel that the other party has become cold.
