What is the religious ruling on a husband's refusal to keep his wife under his marital bond, despite her waiving her right to overnight stays and her desire to preserve the stability of their children after the third divorce?

Divorce is permissible when there is a need for it. The husband's refusal of the proposal to remain married and marry another woman is not an injustice to his children if he fulfills his duties towards them. Nevertheless, it is recommended not to divorce for the sake of the family and children, especially when there is an alternative.
