You essentially had a date with this other woman, no different than if you'd walked into a bar with a few friends and spent your time there in rapt conversation with a stranger. It might not have been planned on your part, but it happened.
NOPE.
It's very difficult for some posters to not show more concern for a female cheater than a male betrayed spouse.
It is what it is.
The error Chamomile Tea keeps making is that she is judging you and your wife's actions by the same standard. Like you are on equal footing from a moral standpoint. But you are not a cheater and a liar, and your wife is a cheater and a liar.
You were not in "rapt conversation", so forget that loaded term deisgned to make you look like a bad guy. "Rapt" is more like what your wife was doing when she was texting the other man.
It sounds to me like you spilled your guts a little bit. Because you are all fucked up due to your wife's shitty behavior.
You're a human. You are not perfect, not that you did anything wrong. Some posters want to judge betrayed spouses so much more strictly - when the betrayed are men - than the way they judge cheaters - who are women.
I think I recall this same poster saying you should have expected to be lied to further after your wife swore she was telling the truth. And if you didn't want to put in the work while your lying wife continued to lie, then well, she was better off without you.

YOU DID NOT GO ON A DATE WITH THIS WOMAN - at least not as you described it.
A "Date" is when two people make a plan to meet with each other with the "intent" or perhaps just the "hope" of exploring a relationship further.
This does not even meet the definition of a "blind date" which is when two people who don't know each other plan to meet.
Also, you are divorcing your wife. You've made that clear. I am not sure why that is unclear to some other people. Maybe they think your wife is driving that train.
You met this woman amongst your friends. They want to set you up because they consider your wife to be a liar and unworthy of your love.
You spoke to this woman in the context of the impending divorce of your cheating and lying wife who has made it so she needs to take a polygraph because she is just that untrustworthy.
And you let this woman know that you are not on the market now, and probably won't be for a while.
THAT IS NOT A DATE AND YOU HAVE DONE NOTHING WRONG!

BUT LET'S BE "FAIR"
If a year ago your wife had met her affair-partner sleazeball at some group work lunch, and her work friends friends where trying to set her up with him (making them sleaze as well because they would be sabotaging a marriage not anticipating an impending divorce) and she talked to him, and said, sorry, it isn't happening buddy, then: A) It wasn't a date, and B) She didn't cheat on you, and C) She should say something to you because she was in a "happy marriage", not an impending divorce, but even if she didn't she still did not cheat on you!
You might not be happy about this hypothetical situation that your wife handled (you shouldn't be) but in this scenario your wife would have handled it decently.
if it would NOT be okay for your STBXW to get into that exact same situation without telling you, than it's not okay for you to do it either.
This is utter bullshit as well.
You and your wife cannot be judged by the same standard nor should you be operating by the same rules. At least not for a loooooong time. Perhaps you both adhere to the same ultimate rule, of "no relationships while still married", but not the same standard of day-to-day accountability and acceptable situations to be in.
THIS IS NOT A MALE VS. FEMALE THING!! This is a faithful person vs. cheater thing.
And this will probably hold true if you decide to attempt to reconcile.
If you feel you want to hold yourself to the same requirements as your cheating and lying wife during this limbo period prior to the polygraph or if you decide to attempt to reconcile, then that is your prerogative.
BUT!!
You have shown you can be around women and not sext, talk dirty to them, grope and be groped by them, penetrate them digitally, try to fuck them, or send them dick pics.
Your wife on the other hand, has gotten dirty in a car, been over to that scuzzy shitheel's home in secret, and sent "partially clothed" pics (as far as she admits).
What this means is that she can and should be held to a standard of proving she is not fucking around by keeping you apprised of what she is doing or where she is, or that she must not be alone around another man, or she no longer can go out drinking with her girlfriends, etc.
While on the other hand, because you are a person who has proven to be loyal and honest, you may not need to "check in", or keep your GPS on, or you may be able to grab a few beers with your buddies - maybe even with a woman in the vicinity!
Yes, it is an imbalance. And it sucks big-time.
The real question is not about what you and your wife "are allowed to do" right now. The question is can you live like that going forward?
