1. Too deep damage: During a fight, one may say hurtful words that hurt the other person's emotions or self-esteem, and the psychological trauma caused by these words is difficult to heal quickly.
2. Trust breakdown: Once initiated, regardless of the original intention, it will destroy the foundation of trust between both parties, and rebuilding trust requires time and effort.
3. Communication barriers: After a fight, both parties may have emotional resistance, making it difficult to communicate effectively, leading to deepening misunderstandings and barriers, and hindering the process of reconciliation.
