Is it permissible to seek divorce due to the husband's inconsistency in providing for his wife and spending time with his first wife and her child, given the wife's feelings of loneliness and psychological distress, despite the husband having a second wife and other children?

If the husband does not act justly between his two wives in allotting nights, and falls short in providing for them, then he is unjust and sinful, and it is the wife's right to seek divorce. However, it is advised to be patient, offer sincere counsel, and supplicate, and to first involve righteous people to mediate. If the husband does not respond, then divorce might be the better option if the marital life has become purely corruptive. If divorce occurs, the well-being of the children must be considered.
