May hovered for awhile in the state between “He’s not cheating anymore.” and “He’s ready to piece.” The two don’t always happen at the same time. She set boundaries—he didn’t get all of the benefits of having a wife and life partner until he actually was committed to piecing.
We may disagree on how tough your piecing requirements should be, but if he doesn’t make any changes from what he was doing before the affairs that you can observe and measure, you are setting yourself up for a nearly certain repeat. Cheating may even be easier the next time. You doubtless have areas to work on, and I applaud that work, but his giving up and cheating on you is huge. Working through that may be hard for him, because he’ll face he wronged you and it was unjustified. He’ll have to identify his internal issues and learn new ways of dealing with them.
