I was hoping she would pass. That would have fit in best with your hopes.
But she didn’t...
There are a couple of thoughts that went through my head:
The operator sounds like a very capable one. They are trained to spot things that could mislead or fool the poly. He also sounds like he guards his words... Based on how determined she was to go, and her insistence on going alone... I wouldn’t be surprised if she thought she could fool the poly, maybe by taking drugs that alter the "normal" and "expected" biorhythms the polygraph picks up on. The operators are trained to spot these things, and part of the initial phase of the test (the interview phase) goes into that. He evaluates her as not capable of taking the test, but guards his words on the why she isn’t capable. He can’t prove anything, and doesn’t have to. She either passes the pre-test evaluation or not. She didn’t.
Keep in mind that when the operator is telling your wife what questions you want answered (the list) he has (probably) also made it clear that she can give him an answer to that question BEFORE the test, and then the test confirms it. Like "did you have sex with OM" – so far she has told you no. She could tell the operator that yes, she did and then later on pass the poly with a "yes" when the question is asked.
Like I have repeatedly said: The poly measures honesty. That’s all YOU need – honesty.
I also find it disturbing that she has planned a dinner date with friends and mom shortly after what should be clearly the make-or-break moment for the marriage.
I find it naïve how she twists words around: If all you needed was for her to take the test then she could have gone there with no sense of pressure. She could pass or fail -> she’s taken the test. It’s a logical conclusion that the expectation was for her to PASS the test, and that to pass the test she needed to be honest to you.
Unfortunately – all the above pushes me more towards the conclusion that this affair went further than we were hoping.

I have always viewed the goal for is to get out of infidelity. The goal isn’t R or D, those are just two tracks that lead us out of infidelity. For quite some time these tracks share the same path, and for some time they run parallel to each other. Going from one to the other is relatively "easy" on the early stages – allowing you to jump between them if there is some debris blocking the other path. The further along you go, the gap widens and the benefit or interest in switching paths wanes.
That polygraph... that was a milestone. It’s the milestone where the first significant split on is on track R and D. Failing to pass the poly is telling you there is no trust, no honesty and therefore no realistic hope for marriage. The path of R is blocked, whereas the path to D is open. If you want out of infidelity, then you need to take the turn along that path.
Worried – the absolute worst thing you can do now is feed drama.
Remember the story I shared about the hurt child with the spouting artery? Enter that mentality. Go about your daily tasks, start gathering your tax returns, banking statements and all that. Don’t go along drama-loaded threads like "I want you to move out" or "I’m looking for an apartment". Don’t go around house all sad and broody. You finally have a plan, you are finally gaining momentum out of infidelity.
Divorce is a process, and it takes time. You can create a list of things that need to be done. Like your kids need to be informed, CLOSE family too, future plans adapted or cancelled. Practical issues.
Your wife? She goes at you then you answer with some basic statements:
The issue isn’t really if you had sex with OM or not, the real issue is your inability to take and pass the poly. That shows there is no trust from you to me, and it also lets me know I can’t trust you. A marriage without trust is dead. If you really wanted this marriage you would be honest, and be willing to validate that.
And
I’m sorry you feel that way. If we were working on our marriage we would have to look into this issue but since we aren’t there isn’t really any need for that.
And
I am too emotionally attached to this family and marriage to talk about details of divorce. I will decide how I want to proceed and what demands I will have once I have consulted my attorney
And in each case – move out of the situation.
For others that butt in:
My wife isn’t being honest about the affair she had at work. I have given her a path to be truthful and how to best verify that, and she hasn’t accepted that path. I can’t build a marriage based on this level of mutual distrust
Other than that friend – spend time with the kids, be mobile, get out of the house.
