to the best of my knowledge, it's when the alcoholic cheats on/leaves the person they're with for someone they meet through AA or rehab... (i think?!)
NO. NO. and NO
One of the first things my sponsor warned me about was 13 STEPPERS.
Huh???
Answer. People who appear to have long time recovery, who use the 12 steps to get into your pants.
Usually, those of us that had sponsors, were steered clear very quickly and our sponsors would take the 13 stepper aside and have "a chat." Also, there are those that are "chronic" 13 steppers.
Hey, it happens in bars, in places of employment, everywhere, why not in AA or NA. It is on the individual.
13 stepping does not necessarily refer to 'cheating.' It refers to someone, 'who should know better,' using the program of recovery for a "new conquest."
