2. Nostalgia in comparison to reality: After experiencing a new stage of relationship or life, men may find that their new partner or current situation is not as good as their old love in certain aspects, such as shared memories, level of understanding, lifestyle habits, etc., thus reminiscing about the time spent with their old love and prompting them to reconsider their relationship with their old love.
3. Growth and Change: Over time, men may experience growth and change in their own personalities, values, life goals, and other aspects. These changes may make him realize that his old love is the more suitable person for him, or he may learn how to better cherish and maintain a relationship, so he decides to turn back and seek reconciliation.
