What should I do regarding my husband who has continued to communicate with another woman despite my attempts to keep him away from her?

A husband's relationship with a woman who is a stranger to him is a reprehensible act and a sin from which he must repent. The wife should advise him with wisdom. The wife has the right to demand her legitimate rights, but she does not have the right to ask for the divorce of his other wife, because the Prophet, peace and blessings be upon him, forbade that. So, she must repent if she has done so. We advise the wife to handle the matter with wisdom and not to rush.
