Sorry this ran long, but I feel you need to hear it.
TPIR, the only reason your thread is 13+ pages longs is you haven't done anything to make significant change. There is lyrics from song "...Even if you choose not to decide you still have made a choice..." The only thing is you are not going to like is the result.
You believe what your wife says with out validating it yourself, and have taken it as gospel. I don't know what you do in your job; but If A is false, then B doesn't matter.
Basic logic. If I lie to you, then what is said "as truth" really is a don't care.
Calling infidelity an affair sounds "too polite"; to me always sounds like cheater-speak. The real term is cheating.
You as the BS played by the marriage rules, and the WS does not. THEY LIE to You. They will lie by omission, flat out distortion with some truth mixed in to sound plausible. They will use people, manipulate you and the ones they love.
She is cheating the marriage vows. You are playing by the rules, and she is cheating to win. You have caught her, so what, since she cheated on the M, she will now cheat by lying to you.
An affair is a fantasy world, but the betrayed also lives (Initially) in a fantasy world by believing the person, that was suppose to be their partner in life, IS NOT right now. In order to make any progress you have to stop living in the Fantasy pre-Affair world. The M before the A does not exist right now. Once you destroy the A, then you have a chance at rebuilding close to what you had.
When she stepped out onto the Affair boat, she destroyed that dream that you two would be together with no THIRD person in your M.
This has already happened. I can put serious money she has (based on what you have written), she has had sex with him multiple times. I know right now you say "that doesn't matter". That's because you are still in SHOCK, this phase will diminish in about 1 to 2 more weeks (normally). Shock phase from D-day about 2 to 4 weeks on avg.
Even now this phase I remember the most, I did nothing, I could barely eat or sleep. I just kept wanting it to go away as if it had never happened. But you know deep down no wishing in the world can undo it.
The bigger picture is stay in denial, and things can go far worse. There may not be a "Cheaters's Handbood" but there might as well be. All cheaters have roughly the same basic personality. Do nothing and she will lose respect for you. She more than likely will go back to the affair. If she hasn't had sex, and based on "the weekend" she has, she will go full bore with him.
I give it maybe 3-4 months on the outside before you notice a change in her demeanor, if YOU DO NOTH(NG.
There is a reason for 13 pages everyone tells you to tell the OBS, besides being morally right. It puts another set of eyes on the A. It forces POSOM to focus on saving his ass. It forces him to tell his wife nothing happen.
Oh??? wait a minute, the OBS would know from you her H went to a hotel with your wife, Oh honey (OBS), she (your WW) pursued me, it wasn't my fault, blah blah blah.
Next your wife sees the POS OM for what he is when he throws her under the bus.
Lost, the huge tell on how bad the affair got, is when after the OBS knows, your WW comes to you and says "YOU blew up the OM's world apart", or is just downright angry at you. This will be your wake up call.
Then you polygragh her, not because you want to know play-by-play sex escapades, it's because you will never recover totally not knowing the TRUTH.
Right now you ignore everyone, imagine you are isolated, and you have a major wound, you're bleeding out (that blood is your marriage).
Everyone tells you what First Aid you need to do (we can't do it for you). Instead of doing anything you just tell everyone that you are not going to do it. This is your right, it is your life and you M. Just remember you kids future relationships/marriages is based on what they learn from their parents.
If both you and your wife continue this behavior it will impact your kids, it did impact my DD.
Writing back to defend this won't matter to me. You are starting on your affair journey, Mine has been done a long time ago. I already have a good idea how yours will turn out.
Back when my A happened I told no one, I had no place (like this) to go to that I felt like I could saying anything. The ONLY thing I did right was eventually doing something, AFTER the PA was full blown.
Like you I floundered in disbelief, and the A progressed further and further into a shit hole. They took it underground (sort of). They still made mistakes.
Your journey out of this only begins with the first step. Right now you have just stood in one place, and wondering why it still keeps hurting. I hope you just don't just stand there and bleed out.
