When I was in training to become a Licensed Chemical Dependency Counselor, we studied codependency. The addicts, including alcoholics, stay in their addiction because they have chief enablers. In codependency, the addict always has to have his/her chief enabler. If the addict loses a codependent, chief enabler, s/he looks for until s/he finds a new chief enabler. An addict does not survive without a chief enabler, doesn't survive without being in a codependent relationship. My mother enabled my father to remain in his alcoholism even though he went to AA meetings and she went to Alanon meetings.
I never heard either one of them talking about "working the Twelve Steps." And, for sure, my father never verbalized working Step Nine, "making amends" with those whom he'd harmed----his kids whom he physically, verbally, and emotionally abused. Dad never told any of his kids, including me, that he was sorry for his abusive behaviors. And Mother never told us kids that she was sorry for not protecting us. And we, of course, became Adult Children of Alcoholics (ACOAs). There's a Twelve Step program for us, too.
The chief enabler (now, I mean, generally speaking) doesn't have a sense of self. The chief enabler hasn't ever asked him/herself, "Who am I?" There's no self-concept nor self-awareness; therefore, there are no boundaries between the chief enabler and the one whom the chief enabler is enabling. There can't be! And the chief enabler doesn't understand the concept of "taking care" of one's self because there is no self to take care of.
It takes a lot of courage and hard work on the chief enabler's part to challenge and then extinguish being a chief enabler, moving past codependent relationships. My mother would deny that she enabled my father staying active in his alcoholism. She denied being a chief enabler just as he denied being an alcoholic. She was proud of taking care of, enabling him. She thrived on her keeping him dependent upon her for his every need. Keeping him dependent gave her meaning and purpose. She had none for herself. So, my parents were an excellent example of codependent living. Codependency always requires a dependent person being taken care of by a chief enabler.
