1) She has been entirely consistent since our conversation where I said I needed the whole truth after D-Day.
Worst evidence ever. In fact, it is not evidence at all.
2) The exchanged text messages between them corroborate that nothing physical happened/they wanted to do more and hadn't.
That is evidence! I forget, did you ever recover her phone using Fonelab?
Some cheaters get very clever in trying to cover their tracks.
3) When I eavesdropped the conversation between WW and WF, they were pretty specific in their infidelity and actions. Once again, my WW was consistent to the extent of the A with no reason to be hiding. This information came along with a great deal of rather bad news, but it was corroborating of the original story.
This is also not evidence. Cheaters like to lie to everybody to make themselves seem innocent.
Don't think she might not have been on to your eavesdropping either.

Let me circle back to this bit:
2) The exchanged text messages between them corroborate that nothing physical happened/they wanted to do more and hadn't.
Weren't they having their affair while traveling away from you?
Two grown adult BOTH "wanted to do more", but nothing physical happened? They just decided not to?
And she is still working with this upstanding moral gent as well?

This is really easy to settle. Tell her you 99% believe she didn't fuck him, or have any sexual contact with him, wanted to but "didn't do more".
But just to satisfy the 1% that isn't convinced, you just need her to take a 1 question polygraph, where she states she did not do anything sexual, which includes but is not limited to:
- Making out with him
- touching her mouth to him in any way, or his mouth to her in any way
- Giving him a handjob or touch her hand to his dick in any way
- Letting him touch her breasts in any manner
- Grinding on him
- letting him diddle her pussy externally or internally.
- Grabbing her ass
- sliding his hand into her pants, either over or under her underwear
- Sucking his dick or touching his dick with her mouth or putting his dick in her mouth, face, or any other part of her body
- letting him rub his dick on her pussy over or under her clothing
- Putting his dick in her pussy or even against her pussy, even for a split second, even "just the head".
- Touching her asshole in any way
- Sticking his finger or dick in her asshole
- Sending any kind of intimate pix, anything from short skirts, to underwear, to lingerie, to partial or fully nudes, to her demonstrating sexual activity
- Or anything else like that
That oughta 'bout cover it. Maybe our poster friends can add to the list.
But if what she is telling you is true, and she has been so consistent, she should be willing and able to answer that one question.
Don't you think?
