part of the recovery and reconciliation process of recovering from an infidelity is that the wayward one has total transparency (thanks transformie, learned that on that site)..that means that anything he has or does...any communications, emails, texts, phone messages, passwords are available to the betrayed member so that they can see what is going on...to help rebuild trust.
This is not recommended for addiction..it is crazy making codependency. there are two issues here.
