It seams to me, the key is loving God more than you love your spouse. Remember loving God means loving His commandments. (1 John 5:3)
God's word contains principles that can resolve almost every marriage conflict. If your love for God and His standards comes first, you will love and cherish your spouse and always show then dignity and respect. And above all, you will honor the sanctity of the marriage union, which is one of God's standards, and not fool around with someone else by committing adultery.
I heard that PMS is the cause of a vast majority of divorces: PMS stands for Power, Money and Sex, these three subject come at the top of the list for reasons of a divorce.
Power struggles or headship problems can be resolved by putting love for God and His standards first. Although not easy, that nevertheless is God's standard, that the male has loving headship over the house and should apply God's standards administrating that headship.
Money problems are so diverse, especially now with the economy in shreds, but love for God and His standards would cause you to place the welfare of the family above any personal desires that are not as important as feeding and clothing the family.
Sex, sexual incompatibility is quite common, but love for God and His standards of compassion and selflessness would make you more sensitive to your spouses needs, instead of just demanding your own way.
I am quite sure that love for God and His standards can sort out almost any marriage problem! The question should be really, how much do you love God to make your marriage work.
