In psychotherapeutic practice, we are sometimes confronted with female patients suffering from a disturbance which is all too lightly categorized as “typical female masochism.” In other words, these patients are not only entrenched in what for them are unbearable relationship structures, in which they are physically and/or psychologically abused, but they also decompensate suicidally if the relationship is terminated by a partner. A similar reaction often recurs in the therapeutic relationship. Whenever the subject of ending the sadomasochistic relationship is dealt with in the therapy and the patient is faced with thoughts and wishes of separation from her partner, the inevitable result is a production of the “weak and helpless therapist,” and the patient threatens to break off treatment. The complicated and seemingly contradictory connection between suicidality and the sadomasochistic relationship arrangement is presented and interpreted with the aid of a detailed case study.
