Is the wife sinful for refusing sexual relations with her husband who commits immoral acts, while she despises him and is repulsed by him, and is harmed by him physically?

It is permissible for a woman to seek divorce from a dissolute husband. If he refuses the divorce, she can take the matter to court or seek khul' from him by forfeiting her dower. Child custody is with the mother until the age of seven, and then they are given the choice. A dissolute person has no right to custody. If the woman is compelled to remain with a dissolute husband and fears harm and diseases from cohabiting with him, then it is permissible for her to refuse cohabitation. It is better to agree with him to remain together without an intimate relationship to waive his right to cohabitation.
