Codependency
Codependent relationships are a type of dysfunctional helping relationship where one person supports or enables another person's addiction, poor mental health, immaturity, irresponsibility, or under-achievement. Among the core characteristics of codependency, the most common theme is an excessive reliance on other people for approval and identity.
History
According to disability studies specialist Lennard J. Davis, historically, the concept of co-dependence "comes directly out of Alcoholics Anonymous, part of a dawning realization that the problem was not solely the addict, but also the family and friends who constitute a network for the alcoholic." It was subsequently broadened to cover the way "that the codependent person is fixated on another person for approval, sustenance, and so on."
