Premanand Maharaj Ji
What should I do if my spouse is bitter and never satisfied, even though I try my best?
Hold to dharma with patience
If a wife regards her husband as her husband and looks toward no one else, he should care for her however bitter her nature, and not move away from dharma. Never hit or abuse, and walk with great patience.
Dharma has great power. Dharma protects those who protect it. One day she will become favourable to you, because you are walking in dharma.
