Can a wife who agreed with her husband to limit herself to financial support without cohabitation later revoke her condition and demand her right to cohabitation?

A wife may waive her right to stay overnight with her husband's consent. She can retract this waiver because it is renewable and due to potential harm she might incur. If she retracts it and her husband does not fulfill her right to stay overnight, she may seek divorce. It is important to note that a wife is not permitted to leave her husband's house without his permission, unless there is a legitimate شرعي excuse; otherwise, her departure will be considered disobedience (nushuz).
