In order to support a recovering behavioral addict, the family needs to understand that they need to pull back and give the person that's working on their behavior the time and the space to go to meetings, to go to treatment, to go do homework, to go and take on things at, perhaps, their own pace, to not necessarily expect them to finish a treatment program and go back to work the first day, and to not necessarily see that they (meaning the family) are innocent and have no ability to contribute.

"It's all the addict's fault" -- the reality is all the family have colluded, enabled, whatever term you want to use, in some way to bring about this phenomenon, and the family should sort of back away a little bit and be willing to talk more openly and own some degree of the problem that has evolved, but looks like it all exists in the addict himself.
