One of the most harmful things to a marriage (or any relationship) is selfishness. Selfishness in marriage will deteriorate a marriage quickly. Demonstrating the golden rule is essential. Do unto Hubby what I would want Hubby to do (or act) unto me.
Do not let your relationship turn into one person only being dominant/submissive-share each role, it will turn into an unhealthy relationship otherwise. Use "I see it differently" in difficult relationships.
