I don't think you are going to get past this if your H is still working with the OW. I would have a terrible time with that situation. He is vulnerable to repeat the A--if he realizes it or not. If he has depression problems....that makes it worse. If he has an argument with you, then it will be tempting to turn to her again. Is there anyway that he can avoid working with her?
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
