Is what the questioner is experiencing considered a trial that she must resist, or does she need to visit a psychiatrist, especially given her rejection of her husband's approach despite her feeling that she must obey him, and his change in dealing with her after she became more religious, and his anger at her religious practices, and his neglect of prayer, and her desire to separate from him?

It is recommended to be patient with the husband, obey him, be gentle with him in advice, and choose appropriate times for that. She should fulfill all her duties as a wife, while frequently supplicating for his guidance and righteousness. It is preferable to involve some righteous individuals to advise him, and not to despair of advising him. She must frequently seek forgiveness, supplicate, show humility, recite the Quran, and read about the lives of righteous people. A woman is warned against seeking divorce without harm, for the Prophet, peace and blessings be upon him, said: "Any woman who asks her husband for divorce without any harm, the fragrance of Paradise is forbidden to her."
