Communication. Telling the other person how their actions make you feel. Not in a descriptive way and definitely not in a way to intentionally poke at them. Basically telling them that what they just said or did made you happy or made you feel belittled, etc.

That is what I am learning right now. I have a wife who has to always be right, can never admit when she is wrong, has little empathy for others, will not listen if something does not interest her, makes rude comments that hurt others and doesn't realize they hurt, if it is not her way... she gets mad, if you get mad at her... it makes her mad because nobody has a right to get mad at her, and lastly.... everyone does everything wrong except her like driving or fold laundry or doing dishes, etc.

By saying what you feel, it can change how that person acts towards you. After learning this idea, it has already made a difference in our ten years of mostly not so good marriage.
