1. Subtle changes in language: frequent mention of a woman's name or deeds, with unusual interest or attention in tone. Unconsciously comparing yourself with that woman in the conversation, especially emphasizing their strengths. Occasionally expressing admiration or envy towards that woman during the conversation goes beyond the scope of general social etiquette.
2. Behavioral changes: Often appearing nervous or avoiding your gaze when using a phone or computer, especially when receiving messages or emails from a specific number. Spending more time outside or alone in a room, and being vague or unwilling to disclose specific activities. Sudden changes in daily habits, such as changing the style of clothes, hairstyle or starting to use new perfume, may be to attract someone's attention.
3. Emotional and attitudinal changes: Decreased care and love for you, appearing cold or absent-minded. Lack of interest or decreased participation in discussing future plans or family affairs. More likely to argue over trivial matters, experience significant emotional fluctuations, and sometimes appear restless, possibly dealing with inner conflicts and struggles.
