Is the wife considered sinful towards her husband if she returns with her children to her home country due to her suffering from alienation and problems living with her husband's mother, despite her husband's apparent approval and inner disapproval, and the possibility of them meeting twice a year?

A woman resides where her husband resides, unless she stipulated in the marriage contract that she would not leave her country. She is obligated to obey him if he asks her to move and live with him. It is permissible for a man to travel with his wife if the path and the destination are safe. If the husband permits his wife to return to her country, there is no sin upon her. However, if he is not pleased with it, she should not proceed with it. It is preferable for her to stay with him to preserve the family and raise the children. She can communicate with her family and visit them. A wife has the right to an independent dwelling that no one else shares with her. However, if this is not possible, then patiently enduring the presence of the husband's mother therein brings great reward, helps the husband honor his mother, and pleasing Allah brings ease.
