1. Lack of freshness: Being in the same relationship for a long time, daily trivialities may mask each other's shining points and reduce attraction.
2. Inconsistent personal growth: The growth rate of both parties in interests, values, or life goals is not consistent, resulting in a decrease in common topics and a weakened emotional connection.
3. Neglecting personal charm: Over reliance on the other person in a relationship, neglecting self-improvement and maintaining personal charm, reduces attraction to partners.
