And what happens when OM comes crawling back to your wife, telling her how FOOLISH he was to have hooked up with someone else, and how no one else has ever done it for him like she has, and how she's the only "true love" he's ever had, and generally says ALL of the things that pushed her buttons to begin with, then what?
I see your wife's remorse to be more of the "I'm sorry I hurt you" variety than of the "I genuinely realize that I did something very wrong," and I see your hope deriving way too much on what your wife currently feels (or doesn't feel) about this specific OM. And I think how she feels about him is deriving almost entirely on HIS moving on, be it for another woman, or disgust over your wife's STD, or feeling she has too much baggage, or some combination thereof.
That can WORK, but it can also be short-lived unless she addresses the root causes of her decision to have an affair.
