On a small point, I was thinking about your timeline for Nov. 5, 2016. That was a Saturday. You were at an event alone, and your WW did something other than what you did.
You know that, almost immediately when you left home, she was on the phone with the AP and, when you returned inside, she hung up right away and acted suspiciously.
She told you that the AP came over for a bit, dropped off his kid, stayed for some period of time, then he left, and she left to go to her 50th birthday party event.
Do you recall if, at the time you left, she was about ready to leave the home? If it was a special occasion like a friend's milestone birthday, she would likely have invested some time cleaning up, choosing and outfit, putting on makeup, doing her hair, etc. Where was she in the process when you left the home?
You say that you recall returning home about 9:00-10:00 p.m. Objectively, that's a somewhat early return for a Saturday evening, especially where you had to drive to a distant place for your function. Why did you return home so early?
You say there is some confusion about whether you arrived home first, or she did. Assuming she was made up and dressed up for her event, she would have likely spent a fair amount of time getting undressed, putting her event-specific outfit away, taking down her hair, and removing her makeup.
Do you recall what the state of her clothing/makeup was when you first encountered her that evening? Was she already "broken down" from the birthday party? That would mean that she had been home some considerable time. For example, if you left home at 6:00 and she left at 7:00, and then you returned at 9:00 and she was already home and cleaned up, that means she must have returned about 8:00 p.m. In other words, she could not have been gone from the home very long.
If she came home after you, then there may have been some time while you chatted as she was doing all of her post-party cleanup.
Do you recall whether she took a shower after you got home? Or, did it appear that she had taken a shower before you got home? Showering would not necessarily prove anything, but a person who has recently had illicit extramarital sex normally tries to shower to remove the odors of sex as soon as he or she can before encountering a spouse. This could, for example, explain why she was home so early (if she was fully cleaned up by the time you got home).
Finally, what was your normal in terms of whether the two of you had sex on a Saturday night? If you normally did, can you recall whether you hade sex that night?
On the poly issue discussed in recent posts, I've indicated that my bet lies with "no significant new outright disclosure, but likely inconclusive and possibly ambiguous results that she will try to blame on her anxiety."
I would remind you that you don't need a poly to tell her: "I don't believe you. I think you're lying." Even now, after the single mediated disclosure session, you are free to trust your gut about whether she is lying. It's also okay, if she presses you about the poly ("why are you insisting on this, don't you believe I've told you the truth?") to tell her you don't trust her. She has not earned your trust.
If she were to ask you why you harbor that feeling, you would be within bounds to point out that lying, deflecting, and withholding has been her norm since fall of 2016. Three years. Now, suddenly, she expects you to accept that she has changed that embedded pattern and is being 100% transparently honest? It is difficult to break patterns like that.
I concur with the others about the importance of pondering what you think you might do (keeping in mind the Mike Tyson adage -- "Everybody has a plan until they get punched"). My sense is that, come Tuesday, you'll be pretty much where you are today, with her sticking to the timeline she has given, but you plagued by nagging doubt about its completeness and/or veracity, fueled in part by the sense that puzzle pieces have been crammed into spots that they don't exactly fit, and in part by the cumulative impact of three years of DARVO/lying/blame-shifting/minimizing.
Really, in the end, I don't see her apologizing and seeking to make amends and help you heal in any real way from the Hell she has put you through. On your best day, I see her continuing to try to be a "good wife" on a going forward basis, hoping that this will be enough for you to simply rug-sweep the past and let bygones be bygones.
That may be enough for you. You have repeatedly described her as a charming, lovely woman, fun to be with, a real gem. To me that sounds forced. A real gem would not intentionally inflict the pain and humiliation she has inflicted on you. A gem would not do that even to somebody she doesn't like, much less her husband.
Your thread drifts through my head often. After wondering about this, I think it's because it is so extreme, even by SI standards, in the degree to which both the AP and your WW appeared to be intentionally trying to inflict the maximum possible insult to you as a man, a father, a paterfamilias, and a husband. The AP coming into your home and accepting your hospitality with the express goal of fucking your WW. Him making advance and her responding to his advances, under your roof, right in front of your face.
By the way, honestly, a married woman gets her ass touched inappropriately by a married neighbor on Halloween and her response is to almost immediately start meeting up with him for surreptitious canoodling sessions, culminating in sex in your marital home just a month later?
Your WW sneaking him into your home to be with your kids, while you were gone. Your kids!
What kind of woman does that? These actions are so utterly heinous. Completely at odds with your description of her as a nice person. A nice person would not inflict that level of insult on her enemy.
I'm hammering on these points because I guarantee that they will continue to float in your consciousness for years, probably decades, assuming you stick with her "bygones be bygones" plan. It won't go away.
This is why I've also hammered home "the Thumos who will be staring you down in the mirror in 10 years". From the beginning of your thread, it has been clear to me that, in the end of this process, you'd wind up more or less where you were when you started posting in August. At present, this is the case. Sure, she got a perfunctory STD test. Sure, she put on a one-woman 1-act mediated disclosure theater for you after making you wait 4 months for it (after 3 years of already waiting). Has she ever just sat down and talked to you about the A, as a wife? I dont think she needed two therapists and a couples retreat to engage in her A. Why does she need that to engage in her marriage? Why does the A come almost effortlessly, while a giant effort has advanced the marriage a fraction of an inch? If she wanted the marriage, she would go for it.
I realize there is the ongoing trauma therapy and the possible Retrouvaille in the spring. You've not talked on these threads about points of light or progress that have been achieved in the therapy sessions. The only point we know is that she did finally give her single disclosure.
What I notice is that you are still not at a place as a couple where you can discuss the A openly and freely at home, outside of the context of therapists. I frankly don't see how Retrouvaille can possible inject life into your marriage if the two of you come to it unable to have unmediated discussions about the A. It is, has been, and in my opinion always will be the elephant in the room that is stomping on your head, while she desperately tries to act as if it's not present.
Remember the rage you felt when you saw the AP at a school function recently. Rage. Dude, you're holding that inside. It's like drinking acid and trying to keep it down. Have you ever let your rage out at her, directly? In JFO, some of the earliest advice to BH's is to live your rage. You have mentioned that you've been hitting the bottle a bit more and the iron temple a bit less. That's not an accident. Your soul is unwell. The bottle is a refuge for an unwell soul.
On another item discussed above - the impact of D on children - I'm aware of the data, but I'm also aware of many successful children of divorced parents. Elon Musk's parents divorced when he was about 9. He was sensitive child, and small. South Africa in the 1980s was a violent, fucked up culture. Elon has done okay.
