Thanks everyone for your helpful replies and support. This is a good place.
First, I want to answer a few recurring questions and clear a few things up.
I am still in shock, definitely grieving, and quite depressed, so what I post here takes on the form of a ‘report’. Especially with two of my last posts, where I had a lot to report, it was easier to cite the facts and not dive too deeply into my responses to them.
But to be clear: no part of me believes the masturbation story. Okay, that’s not 100% true. I mean: it seems so odd a story, and frankly somehow more embarrassing than them just having straight up sex, that part of me believes it. I know that that belief comes from a wounded, misguided place: a stupidly hopeful place, thinking, ‘Well, if they haven’t had p-i-v- sex, maybe this is somehow salvageable…’. But overall, it is risible in the extreme and hopefully, one day, when I have much much greater distance from all of this, I will actually be able to generate laughter at its thought.
Second, I should clarify that under no conditions will my wife be visiting me here. I reported that because that’s what she said. My actual response to her offer was to say that I consider that a deeply manipulative ploy on her part: that the very source of my agony—her deliberate withholding of sex to me; her choice to have sex with another man—is somehow to be turned into our salvation. I told her she was sick and needed help.
I should also clarify that OBS and I have both told our spouses that we have seen the Word doc in its entirety, and that we have proof of their overnight at the hotel. Sorry. I forgot to mention this. My wife initially had the cheek to berate me for ‘snooping’ in her computer. I calmly pointed out that there would have been no need for me to do so if she had proven herself to be a trustworthy partner.
Finally, with regard to my wife’s previous marriage: I don’t think there is any ‘fire’ or even ‘smoke’ there when it comes to infidelity. They had plenty of issues, but her having a wandering eye wasn’t one of them.
Ultimately, where I am at this very moment is that I am through with her. Everyone has different thresholds, especially around betrayal; for a variety of complex reasons, infidelity is, for me, one of those irrevocable sins.
If you asked any of the women I have dated in my lifetime—whether for a few months or for several years—while they might be happy to share many of my flaws (!), one flaw they would NOT cite is "poor communicator." I am of the profound belief that good communication is the heartwood, the core, of all healthy relationships. And that, above all, infidelity is not—ever—a means of working through problems. You should be able to communicate through any problems.
What I have extracted from the hundreds and thousands of helpful words written to me here is this, above all: when it comes to the wake of infidelity, and when the betrayed evaluates the betrayer’s suitability for any form of reconciliation, actions are everything.
My wife’s actions—from the outset and right through to this moment—convey utter disrespect and a complete absence of remorse. I wrote these very words to her not a few hours ago. (She has yet to reply.)
Where I am at this moment is that I will be serving her with divorce papers next week; I will ask for no contact from her for several months; and I’m going to proceed with the expectation that this relationship is unsalvageable.
That all said, I don’t know how I would feel if—out of nowhere, and unexpectedly—she started displaying all the actions associated with the ideal remorseful cheating spouse. Though, even if she did, it may well be too late.
