I think if my H comes back because I exposed at his work, he's not going to be the man I want anyways. Exposing at work is really another attempt for me to control a situation that I think I just need to accept the situation as uncontrollable.
How to quit an addiction: 1)must be removed from access to the substance 2) will go through withdrawal 3)must stay away from the substance no matter what 4)after detox, you will no longer be physically addicted, but will have "triggers" 5)must never go back to the substance again
OK this is super simple explanation of how to quit addiction, but here is why I am posting it. AT FIRST your H may not be coming back to you "for the right reasons" BUT AS LONG AS HE STOPS COMMUNICATING WITH OW, he WILL lose his attraction/interest for her, and it you will see him thankful he is with his family.
They say it takes awhile because they have to go through withdrawal from the OP.
