In this article, I explore the dynamic underlying a very common contemporary phenomenon—the creation of an additional intimate relationship, while remaining in another stable self-dyad. This phenomenon is discussed via the unconscious and conscious perspectives of those who initiated and actively engaged in the additional relationship. In the absence of a capacity for verbal communication about emotions, the additional relationship serves to enact powerful, infantile needs, that were not met or processed in infancy, and which therefore vigorously re-emerge in the adult intimate relationship that lacks the capacity to contain them.
