What is the Sharia ruling on a husband who insults his wife, does not acknowledge his mistakes, belittles her in front of others, interferes in her private affairs, watches forbidden things, and talks about other women, which negatively affects her psyche and her relationship with him?

The questioner's complaint is limited to the husband's dereliction of her rights and the rights of Allah. She should be patient with his shortcomings regarding her rights, try to advise him, remind him of her rights upon him, overlook his mistakes, and not reciprocate his ill-treatment or refuse his bed. As for his sins and transgressions, she must remind him of Allah's limits and warn him of His punishment, while also beautifying herself for him. If these attempts are not fruitful, she may seek a divorce or refer the matter to the Shariah court.
