What I've been learning lately:

"Civilized arguments can benefit a relationship by exposing neglect, unrealistic expectations, or different points of view. Sometimes, neither person is wrong. Each one is simply approaching the same topic from unique perspectives. Therefore, do not try to avoid conflict but seek to resolve it in a loving, mature manner. If you cannot freely voice your opinions, you will live in miserable bondage to another person. Both parties should have the freedom to express their ideas and desires." link

Oh yeah, and prayer works :)
