1. Deepening emotional resonance: With the passage of time, the husband and mother-in-law have experienced more things together, which may have established deeper emotional connections and resonance in their daily interactions. He began to better understand and appreciate his mother-in-law's thoughts and feelings, so he tended to speak from her perspective in discussions or conflicts.
2. Family role cognition: As a member of the family, your husband may gradually realize his responsibility in maintaining family harmony. He may believe that supporting certain viewpoints or decisions of his mother-in-law can help reduce family conflicts and promote family harmony. This role cognition makes him more inclined to support his mother-in-law when choosing a stance.
3. The influence of communication style: If your husband finds that your way or attitude may escalate the conflict in your communication with your mother-in-law, he may adopt a more neutral or biased stance towards your mother-in-law to mediate out of consideration for protecting the family atmosphere. He hopes to balance the emotions of both parties and avoid escalating the conflict through this approach.
