I don't know what the opinions are here about spouses and other persons. In my opinion, anything the wayward spouse says or does while they are in continued contact with the other person, is suspect.
Actions that match words are what count. If your husband says that he wants to work on things, and he then breaks it off with no contact - that means that his email password, cell phone and all other communication venues become open to you. In essence, his life becomes an open book to you. Only then would I believe that he really wants to work it out.
You must understand, he will do anything he can think of to make himself feel better about what HE is doing. In truth, for the wayward spouse, little to nothing of what they do, arises from any consideration whatsoever of the betrayed spouse.

I will ferret out an affair at any opportunity.
