guss,
I rarely venture into JFO. The raw emotions still bother me too much almost 2-1/2 years after D-Day but your thread caught my eye.
From what you wrote, it sounds like there is a lot of rugsweeping going on. She is either trying to sweep it under the rug to ignore that the A happened at all and not have to answer for it or is cake eating and has taken the A underground. Have you looked for secret e-mail accounts, burner phones that she has hidden? Is she away doing stuff with friends or alone for long periods of time? Can you verify that she is actually doing the things she claims to be doing?
My XWW (I hate using the word my in front of that) got very involved in hiking. I was not allowed to participate or even to get to know her friends except for two women. One day she left for a weekend camping. I got suspicious by some of her actions, opened her computer and found her e-mail open and learned that she was meeting OM for the weekend and using her BFF as a cover. The BFF was furious but had no knowledge about it.
Your WW (she has not earned a f let alone a F) is unremorseful. It sounds like she is not willing to do the work to heal from this A. and to make amends for the pain she caused you. Is she reading any self-help books? Is she going to IC? Are you in MC? If she isn't doing the work then she is NOT committed to your M. She is just passing it off hoping you will let it drop.
XWW was very non remorseful. Once I confronted her she was blatant about dating her OM while refusing to leave the house. We were in home separated for 7 months and it was hell.
Make her write out a timeline. Don't look for the sexual details - I know that would be too painful for me but make her own up to how often she and OM met how much of it was EA and when it became PA. I do not believe that she was with someone in an EA for 3 years and it only became physical once.
Is she still in contact with this guy? Are you sure? Has she written a no contact letter? First it was all 8 years of your M, then you found out that it was 3, how do you know? Why would she suddenly stop after successfully keeping it from you for so long?
I am pushing on this because unrepentant WSs are major liars. For 12 years XWW was repulsed by lying. Then I found out just how skilled of a liar she is. And long past when it mattered and even for stupid stuff.
I strongly suggest that you try to detach. Look up the 180 and hold to it as best as you can discussing only money and children until she starts showing that she is working hard to save you M. It is YOUR choice whether to give her the gift of R. Not hers. She needs to earn it and to earn your trust again.
I know because your response to this is exactly how I wanted to respond except XWW would not have anything to do with me. It may be easier but it is just abuse towards you and that is not right.
Above all, remember that it is her actions that matter. Her words are empty.
Go down to ICR to the Betrayed Menz forum. Those guys rreally have a lot of good advice pertaining to R and getting through this shitstorm that was forced on us.
Good luck to you buddy.
