Need some help with moving forward.

Let me clarify a bit on my last post:
When I threatened to go to the OM's W, my W finally said that she would cut off all contact. When I asked her if protecting him was the motivation behind that, she of course said no.
At this point, I have no idea whether the OM's wife knows anything (I have been given conflicting stories about that by my W. "she doesn't know", "she's suspicious", etc., and it all seemed to be dependent on the conversation that my W and I were having.)
As far as I know, the NC period lasted for about 3-4 months. When I found out, I didn't contact the OM's W, etc. So, it at least worked for a bit, but I didn't follow through, because it was months later.
Anyway, any advice is appreciated. I've seen varying opinions on this matter here.
