Hdybrh,
I wish you luck, whatever happens. Everyone on here has their opinions and some seem to be going so far as to project some of their own anger onto your situation... Definitely not helpful.
The thing we all need to realize is that from the get-go, you both seem to want to pursue the goal of staying together. The old marriage IS dead. However, there are plenty of people in the Reconciliation area of the forums who made the conscious decision you and you wife want to try to pursue. I was going to suggest that you might want to head over there and maybe read and get some advice to see how some of their journeys started and have been going/have gone.
It has been 5 years since my world got destroyed by my WH. We were married 13 years when it happened. We did not make it. However, to this day I do not see things as black and white with how affairs start, how they get justified, how they are talked about or thought about afterwards. Some are muddy, some are clear. Some stem from simple situations, others from years of underlying problems.
Some things I DO believe are pretty black and white, however:
1. Trust is an extremely hard thing to rebuild, but with resolve, effort, strength and commitment to the CHOICE of achieving that goal, it can be done.
2. People claim that feelings of dissatisfaction, boredom, depression, etc., make them have affairs. However, as all of us seem to be quick to point out, it is the CHOICE to ACT on those feelings that is the downfall of the marriage.
In the same way, to me, feelings of betrayal, mistrust, disillusion, disgust will exist once an affair has happened... and these do not last forever. It once again comes down to the CHOICE of what feelings you decide to ACT on, that will determine if you divorce or reconcile.
The choice should, of course, be based on rationality: Is this a pattern? Do they seem to be showing remorse? Are they committed to figuring out what inside them allowed them to make these decisions and, even more importantly, are they committed to learning and deciding to make choices for the marriage instead of just themselves?
People can't control feelings... but they Can control CHOICES.
3. Communication and the commitment to put it first and foremost from here on out is essential. Not communicating to your spouse right away at the first sense of danger to your marriage is the biggest problem in my mind (i.e. "We need to talk. I feel like I am losing my connection to you and am finding myself starting to gravitate towards other women. I never wanted this to happen and I want to see what we can do together to try to stay committed to each other in our marriage. Can we see a counselor?"). Trying to "feel" or "figure things out" for Yourself to avoid hurting your partner when you are in a marriage, where the two of you are supposed to be seeing yourselves as one half of a whole, is a mistake.
When your leg gets cut, it doesn't try to hide the pain from the other parts of the body so they won't feel it; it communicates the pain to the rest of the body. Then, if the body is a healthy one, the other parts jump into action to help the leg and keep the body alive: the brain decides the course of action, the hands reach down to clean and bandage the cut, the other leg takes on the weight that the cut leg can't carry until it's healed. But if the leg doesn't communicate the cut or the pain, it can bleed out. It can get infected. Then the entire body and all the other parts that join the leg in making the whole body are in jeopardy of dying.
It's a crude analogy, but the body is the marriage and the parts Need to communicate when there is danger to keep the marriage alive.
I do agree with everyone else about reporting the guy to his profession's board, especially because he can't seem to respect the boundaries that even your wife has now set down about no contact. If he's willing to ignore those boundaries with you and your wife, he probably wouldn't have problems with anyone else's marriage and families.
I do wish you luck again whatever direction you end up going.
