Do you want to recover your marriage, or let it go?
I have no doubt that you are tired of this fight. You have been at it a long time. I don't believe that your marriage is over though, at least until you have had enough.
If your 'gut' tells you that he is doing more of the same, then I would believe that he is doing just that.
It is not your fault that he is doing what he is doing. I do think that spouses BOTH contribute to the state of the marriage, but it stops there. A bad choice is a bad choice, and an affair is a bad choice. As long as your husband is in any kind of contact with another woman, then your marriage is going nowhere, and nothing is going to resolve.
There are a number of different approaches for ending affairs and restoring marriages. I guess that you have tried some of them.
If you feel up to it, let me know where you are and where you want to go. If I can help in any way, I will certainly try.

I will ferret out an affair at any opportunity.
-An affair is the embodiment of entitlement, fueled by resentment and lack of respect. -An infidel will remain unreachable so long as their sense of entitlement exceeds their ability to reason.
