My spouse has delusions abt me cheating on him. when hes angry, he harms me. but never feel remorse abt it after he calms down. y is this so?

Very hard situation: This is a very dangerous situation, and you need to protect yourself. Do you have relatives (from your family, not your husband's) living nearby? In some cultures women are routinely abused, and this is not questioned. Still the dynamics lead to a very unstable, painful situation for the woman. I suggest talking with your doctor in private about this, and reaching out to your family for help.
