In any relationship, trust, respect, and open communication are essential. If a woman feels hurt, betrayed, or uncomfortable with her husband sending pictures of their baby to his ex-girlfriend, it's valid for her to experience anger and frustration.
While sending pictures of their child to others might not be inherently wrong, if the husband's actions are causing distress to his current partner and he continues to do it secretly despite her expressing her discomfort, it can be seen as a breach of trust and disrespectful of her boundaries.
Divorce is a significant decision and should not be taken lightly. However, if such actions continue to cause strain on the relationship and the couple is unable to resolve the issue through communication and compromise, divorce may become an option to consider.
In any case, the best approach is for the couple to sit down and have an honest conversation about their feelings, concerns, and boundaries. It may be beneficial to seek the guidance of a relationship counselor or therapist who can help them navigate through their difficulties and work towards a resolution that is acceptable to both parties.
