There's the rub ~ if our addicts have other enablers to fall back on, their chances to hit bottom get a lot slimmer. I know my XAH is also the King of the Manipulaters,and is able to suck people in for quite a while before they even realize he's got a problem.
But it's important for our recovery that we break the cycle at our end. We can only hope that the other enablers our addicts turn to eventually detach, and that our A's come to a place in their lives where they're ready to deal with the reality of their addiction.
