What are the legitimate and legal measures a woman can take to seek divorce from her husband, who mistreats her, does not provide for her and their children, besides being selfish?

Spouses must live together in kindness and fulfill their religious obligations. The wife has the right to be financially supported, and she is not obligated to spend from her own money unless she volunteers to do so. What the wife earns from her work is exclusively hers, unless the husband stipulated a share of it in exchange for his permission for her to work. If the husband does not provide for her kindly and mistreats her, the wife has the right to seek divorce. However, divorce should be the last resort after reconciliation becomes impossible, especially when there are children. Patience, overlooking minor faults, and focusing on the good aspects of the other spouse help maintain affection and harmony. One should not despair of prayer.
