Wife uneasy about husband's bond with adult daughter

A woman has expressed concerns about her husband’s newfound relationship with his 24-year-old daughter, whom he recently discovered he had. The couple has been married for five years, and the woman feels like a third wheel as her husband spends time with his daughter. She describes their interactions as overly affectionate, with frequent hugs and deep gazes that make her uncomfortable. The woman is feeling jealous and has observed their text messages, which contain loving phrases and emojis similar to those exchanged with her husband. After a weekend together, the daughter and husband returned home late and appeared to be very close. This behavior has left the woman worried, as she fears there may be inappropriate feelings between them. She has brought up her concerns with her husband, but he insists that he is simply excited about having a daughter. An advice columnist responded, suggesting that the situation is a normal adjustment. The columnist mentioned genetic sexual attraction as a rare phenomenon but noted that the significant age difference makes it unlikely. The columnist encouraged the woman to see her husband’s daughter not as a threat, but as someone who can be part of their family. It was also suggested that they invest time in their own relationship to ease some of her feelings of jealousy.
