I think it's also important to point out that being codependent or having codependent behaviors is nothing to be ashamed of. It doesn't make one "lesser than". It's just maladaptive behaviors learned in childhood, previous relationships, or may be developing in currant relationships. One could also just have situational codependency or codependent behaviors.
I know during the "year of my insanity" that I behaved in ways I never behaved before or since. I know during that same year I compromised and abandoned myself over and over again. And, again during that year I ALLOWED myself to be treated in ways that a healthy person would never allow.
Sure, I can pick out dozens of things I didn't do, or didn't allow and think that I was terminally unique or even worse "better than". But, just like with the addict, take the use of drugs out of it, was my behavior acceptable or not. And, for me...no it wasn't.
