Certain patients by their actions complement each other in ways crucial to the general adjustment (rather than adaptation) of the partners. This may be especially true in overt homosexual relationships, destruction of which may lead to symptoms in one or the other partner. In another form of mutual adjustment, one partner derives gratifications from the acting out of the other, encourages and in fantasy shares in the acting out. Others may be drawn together in antisocial relationship because of very similar conflicts and character structure which result from and are ways of adjusting to the conflicts previously created by a hated parent. Marital partners may have the same symptoms, they may use similar or complementary defenses. The choice of object may be determined by the attempt at mastery of a traumatic relation of mother and child.
