Even though codependency consists of acting solely on behalf of a partner's desires, this is not to be confused with care-giving.

As observed by disabilities specialist and author Lennard J.

Davis, codependency as a concept soon grew to refer to any: (Davis).

Codependency describes a type of relationship in which one partner is leaned upon to enable the other person's addictions, insecurity, or emotional instability.

In most codependent relationships, the stronger partner is used to complete the other half's self-esteem or sense of identity.

Commonly referred to as leeches, sponges, moochers, and parasites, many such people could also be described as walking train wrecks, due to the impulses, habits, and poor decisions that lead them from one crisis to another.

Often times, these people stay afloat on the goodwill of others, such as family or lifelong friends.

During the 1980s, codependency treatment grew into a full-fledged field of therapy.

The movement was fueled by the release of two popular books that advanced the topic in the public discourse: Also in 1986, psychiatrist and author Timmen Cermak, M. published two works in which he lobbied the American Psychiatric Association to add codependency as a distinct personality disorder in the organization's Diagnostic and Statistical Manual of Mental Disorders, but this proved unsuccessful (Morgan).

An insecure woman, for example, might have a tendency to fall for callous, macho, alpha-male types who take women like her for granted.
