What is the ruling of Islamic law regarding a man who discovered his wife was having an illicit online relationship with another man while she was traveling, and despite his attempts to rectify the situation and give her a second chance by moving to another country, the wife and her mother continue to justify the betrayal, and the wife requests the freedom to travel alone and use social media as before, in light of the deteriorating trust between them?

The husband is responsible for his wife and must protect her from tribulations, by virtue of his guardianship. What was mentioned about the wife is evidence of her recalcitrance (nushuz). To treat recalcitrance, one should follow the শরعي (Shari'i) steps, with firmness and without heeding her mother's incitement. It is possible to involve wise members of her family as mediators. If attempts at reconciliation are unsuccessful, it is recommended to separate from the recalcitrant wife, or to be patient with her for the sake of the children. Her wickedness (fisq) prevents her from being entitled to child custody. The husband must strive to prevent her from having custody of them, or to take responsibility for their care and guidance himself. The husband must also satisfy his wife's emotional needs to strengthen their companionship.
