I am sorry that I gave the impression that I am rejecting all the input I got here, but that is not the case. I do appreciate a lot of this input -- though I admit I came here initially for emotional support and of course to also get some help and clarity in this chaos that has overtaken my life.
Sure I wasn't expecting all that hard hitting stuff but even that was not all ignored, it already had an impact on my views of the situation. I realize that I have been too weak in my initial approach to the situation, and more importantly that I have to let go (and let her go), that my marriage was over years ago, as others have written here.
In particular I deeply appreciate Okokok's replies who already helped me see things more clearly and forced me to ask myself some very serious questions. (Okokok I'm still pondering over your last message, which was truly excellent, I'll prepare my reply -- I'm agreeing with most of what you wrote there).
I do not believe that I am some sort of smug "highly evolved “renaissance man”", I am sorry if I came off that way. I do believe I have much more "inside information" about my over 30 years of relationship with my WW and yes, about her person as a whole -- I am still certain that she is not "all bad" and I am not ready to make the mother of my children suffer so much by destroying her professional life (which means so much to her, not just because of the AP). I know that she is no longer the same person I married, I read about the psychology of WW etc. I realize she is effectively my "enemy" now in many ways, but not in all ways -- again, we can both compartmentalize, we both want to minimize the trauma for our children now, and amicable separation + co-parenting might be effectively the best way to achieve that.
I don't think it is such a terrible thing to admit that indeed I tried to take the "high road" initially because I really thought (and wanted her to see) that my love for her can be that selfless as to allow her to be happy with the AP because she seems so in love with him. I only asked them to stop the deceit, to take their love into the open, if they think they can be so happy together in the real world, and I'll then bow out..
Of course my mistake was to not really push for including his wife in this situation, when he agreed to have that talk. It was easy for them to persuade me to have that talk without her because in those days my instinct was do contain and even reverse the damage. That was foolish, there is no way to reverse the damage, I got that now. She is too far gone.
Her reaction after Dday was somewhat typical for a WW in a LTA that has no remorse: she kept blaming me for it, not only because I was a terrible husband years ago, but also because how mismatched and "toxic" (for her) our relationship has been even in the last years. She deluded herself in believing that, I understand why. I know that part is not true (and my children know it too) but she used that to keep repeating after Dday that she can no longer love me or continue to live with me because of that etc. So obviously, no chance of reconciliation there -- she's gone. As some of you said, she already chose the AP over me. So doing the "pick me dance" now is really futile. I think she was just daring me to ask for a divorce or something, so she won't be the one to blame that she asked for it.
The children obviously have been way too hopeful about reconciliation and since we're locked all here together due to covid, we had to come to some sort of armistice for this period. Since she did not seem to listen or care about me and what I wanted, but she still cared about what they think and feel, that's why she promised them (not me) to stop seeing him at least for this lock down period. And because I caught them by monitoring her location on her phone, she agreed (reluctantly!) to leave her location on when she goes shopping for essentials or for long solitary walks or with the dog etc. (which she took plenty lately but in a couple of cases she "forgot" her phone at home or somehow disabled her location..). Even after she agreed to NC, and to be monitored like that, she kept complaining that I am controlling, that she never liked that about me, and she hates to be "spied on" like that, that she has no privacy (she was actually crying about these things one morning!). Typical WW cheater attitude, I know. Which brings me to
You have been the victim of a deep network of manipulation, and that hasn't stopped yet. Any "civilized" conversation you have (or are currently having) will still be permeated with lies, half-truths, subtle blame-shifting, and manipulation. She may not even be conscious to the fact that she's doing it, but these things will be happening.
As hinted above, I can already see she's doing that. I indeed stopped trusting what she says -- except maybe the part about supporting her kids through college, that I do believe. I've been also feeling that dread lately, that they have been playing 3D chess behind my back while I was the unidimensional "nice guy" loser stuck on the same line (dot) of inaction. So much for my taking the "high road", I see that now. And I'm planning to stop it -- though maybe not as vigorously as some of the posters here would want me to.
