This paper propose a clinical-theoretical reflection on a psychoanalytic psychotherapy with a young couple of separated parents, and propose a presentation, in the pure meaning of Winnicott, of a clinical experience with its implications and questions. It go through the first year of therapy again and stop on the salient points, on those fundamental cruxes in the background of a complex dichotomy union-separation. The real configuration of therapeutic setting, and the complex construction of its symbolic equivalent, seem to have allowed to this couple the creation of an inner space, third, and the exit from a painful, constant, repetitive immobility.
