1. Emotional inertia: After ending a relationship, men may develop a certain psychological inertia due to the life experiences and emotional investment they have shared with their ex partner for a long time. This inertia makes it difficult for them to immediately detach from past emotions, and memories and emotional reactions towards their exes remain strong.
2. Unfinished complex: If there are regrets, misunderstandings, or unresolved issues during a breakup, men may develop an "unfinished complex" as a result. This complex drives them to constantly reminisce about the past, trying to find answers or make up for regrets, making it difficult for them to truly let go of their exes.
3. Self identification and memory value: exes are often closely linked to men's self-identity, especially during the wonderful times they spent together. These memories provide emotional support and a sense of self-worth for men. Even if they break up, men may find it difficult to forget their ex because they cherish these memories. Meanwhile, the ex may also become a benchmark for them to measure their future partner.
