What is the ruling on abandoning one's mother and father who cause problems that threaten the marital life, knowing that all filial duties towards them are fulfilled, such as care, providing a maid, and fulfilling their requests?

The husband is not obliged to live with the wife's parents. The wife must obey him and move with him if he wishes to do so. There is no harm for the wife in leaving her parents and moving in with her husband, especially if the parents are not in need of her. The mother should be advised gently to avoid problems, reminded of the importance of good relations between in-laws, and warned of the consequences of such problems.
