The basis for some relationships is a balancing act, each compensating for the deficiencies of the other. If either one begins to become whole, the very foundations of their relationship may begin to disappear because they have nothing else in common to hold them together. Any change in one becomes a threat to the other and will be resisted. (Goldberg, Herb, PhD. The New Male-Female Relationship. p 33. NY: Signet Books, 1983.)
