When two people in a marriage are more concerned about getting the golden eggs, the benefits, than they are in preserving the relationship that makes them possible, they often become insensitive and inconsiderate, neglecting the little kindnesses and courtesies so important to a deep relationship. They begin to use control levers to manipulate each other, to focus on their own needs, to justify their own position and look for evidence to show the wrongness of the other person. The love, the richness, the softness and spontaneity begin to deteriorate.
