1. Stay calm and respectful: Handle this emotional expression calmly, respecting the other person's married status and family relationships. Clearly express your understanding of his marital status and emphasize your respect for his family.
2. Clear rejection and maintaining distance: Tell him directly and politely that you cannot accept his liking because it involves emotional involvement from a third party, which is not in line with moral and ethical principles. At the same time, in order to avoid further misunderstandings and troubles, it is recommended to reduce or adjust the frequency of contact with him appropriately and maintain appropriate social distance.
3. Focus on your own life: Shift your attention to your own life, interests, friends, and family, and don't get too caught up in this inappropriate emotional entanglement. Enrich your life, enhance your sense of self-worth, and find true happiness by participating in positive and healthy activities.
