To have a successful marriage requires more than give and take! To really succeed the focus needs to be giving. One of the key principles marriage is preferring your spouse above yourself. To love my wife in the same way as I love myself is probably the single-most important principle that I can strive to excel in. I suppose that is why the Bible has a whole verse encouraging just this.
28 In this same way, husbands ought to love their wives as their own bodies. He who loves his wife loves himself.
