1. Indifference and sensitivity in language: Married men may suddenly become indifferent to their partners when they are jealous, reduce communication, and even indirectly express dissatisfaction with their partners' interactions with others through sharp and sarcastic words. They will be overly sensitive to their partner's words and actions, frequently asking or questioning their partner's relationships with others, especially the details of their interactions with the opposite sex.
2. Behavioral control and monitoring: In order to alleviate inner anxiety, married men may increase their monitoring behavior towards their partners, such as frequently checking their partners' phones, social media accounts, or attempting to confirm their loyalty by tracking their partners' movements. They may also try to limit their partner's social activities, especially the opportunities to interact with people who make them jealous.
3. Emotional outbursts and self doubt: When jealousy accumulates to a certain extent, married men may erupt in anger, arguments, or even a cold war. They may also fall into deep self doubt, questioning their own charm and abilities, and worrying that their partner will be attracted to others. This emotional state may have a negative impact on their mental health and marital relationships.
