The present study attended to identify and characterize the psychic functioning of three patients, treated with psychotherapy psychologically oriented, who lived the permanent or intermittent absence of their father figure during their childhood. There were two adult women and a man who consulted for the difficulty in order to establish and keep partners relationship with men. During the therapeutic process, it was identified that the absence of the father disrupted the process of construction of the thirdness, and with it the configuration of Oedipus Complex, so that the quality of the relationship with the mother and the way she assumed the absence of the husband-father-man role, shaped a way of relation in the pair, mother-son or mother-daughter and it affected the current dynamics in the relationship with male objects. It was found that the predominant relation between the Self and the objects was based on the idealization of the male object and that it disturbed the shape of the relation container-contained presenting adhesive identifications to objects and dynamics of the two-dimensional space of the mind. The therapist fulfilled the role of being the third container object that was done in the sessions, the clarifying and differentiating functions as well as the conscience functions that the third carries out at the moment of triangulation over the dyadic confusing and sensual relationship. The psychotherapy, the supervision and the research were established as activities of triangulation that allowed the psychic development of the patients and the professionals who thought about the cases, opening new fields of vision and comprehension.
