Couples generally fight over three major things ; Sex, Money and Children. Learning to manage this three areas in marriage will help save your marriage.

My father used to say the key to a happy married life is two words. "Yes Dear"

That is the problem with marriage-predetermined events & assumptions. There are no rules, laws or secrets to marriage. Problems might spring up from other angles. Just live your life the best way you can & leave the rest to God. You can't please everybody but you can live life easy. A marriage should be a learning institution on its own, the expectation is the problem. The only thing is that all individual irrespective of whether they are married or not should have a good behavior, a good heart & the fear of God. Don't because of marriage start acting a certain way, if you have always lived a good life, it would reflect in your marriage as you are not forcing it, its already a part of you.
