Mark Michael Lewis explores 3 types of dependence in relationship (dependence,  co-dependence, counter-dependence), the difference between dependence and interdependence, and the potential of interdependence that independence makes possible. He also contrasts the difference between relationships around OTOH the value of our self/person and OTO the value of our skills/actions. Last, he explores the emotional and interpersonal consequences of dependence vs. Interdependence, especially pseudo-intimacy.
