Not everyone unfortunate enough to have sons and daughters alcoholics in their lives are codependents. Read some stickies. If you are one you should be able to to see it.
Keep in mind also that codies are not just people with alcoholics/addicts meshing up thier lives. It's a relationship behavior problem with any individual who isn't "Well". from mental illness to abuse to emotionally unavailable people.
Sooo...
One can be a codependent to say, a "mentally unstable" son or daughter thier whole lives. But, not cater to the "alcoholic" they become.
Not saying that's you! - Just saying that's one scenario. :-)
