Hi Dan,
The guys who provide IT support for the department that I work for have been doing so for a few years. We know each other, we chat by email and messenger (whenever there are problems to fix) and also during projects when the system is being improved or expanded.
You said that this guy was at that office before, doing a project before your wife worked there, so he is probably the 'go to' guy for their IT support. Therefore, it seems likely that even if he was not physically in the office before the beginning of December, there may well have been contact between him and your wife about work stuff that may have become more personal or flirty before he was ever 'in house'.
That would certainly make more sense than him walking through the door as a complete stranger to your wife, and within a day or two she is hopping in a car with him, having lunch with him, getting into clinches with him, and planning for more.
The man was supposed to be working, so how did they build up that much of a rapport within hours of his arrival? And if the majority of the people in the office are female (as you noted at the party), why did he focus on your wife so quickly if she was totally unknown to him? If you walked into an office full of women you did not know, which one would you be taking to lunch the next day?
My hunch - and yes, it is only a hunch - is that there was already a comfortable relationship (via work email or phone) between them before he arrived, during which your wife developed the fantasy that she mentioned. As soon as he arrived, they kicked it into a higher gear, using their own phones for the kind of material they would not want to exchange via work email.
The way it played out was like she was waiting for him to arrive, and the second he did, it was game on. If she already had a fondness for him, and had been formulating her fantasy, it would not matter that he was a bit homely in person, because she had already moved beyond initial attraction in her mind. However, if they were totally unknown to each other, why would she have pounced so quickly on a homely IT nerd that she knew nothing about?
The other element that may give you more information is any location software that might be on the phone. Does it have Google maps, or any other software that might indicate where the phone was? Given the way things were between them, I would want to verify the gym evenings that occurred while the OM was in town.
She is pleading to come home.
It is up to you, Dan, but for your sake it may be better to have her away from you and your home as you get your thoughts together. Also for your daughters.
Whichever way you eventually choose to go, it is wise to get advice from a lawyer so you know how the different options would look.
Your daughters sound wonderfully supportive, bless their hearts. I am glad they are bearing up alright in what must be a tough situation for them. They seem incredibly well-balanced and mature.
Edited to add:
It started when he sent her a text saying "I would love to see you out of those scrubs" and she replied "just different clothes or naked?"
I wonder what his bosses would think if they saw the way their representative behaves with clients? It is no wonder he is being so quiet! If you pressed this, his job would be toast. So I do not think you are going to hear anything more about your discussion with him. He has way too much to lose.
Also, no man - unless he is mentally unstable - would send a message like that to a woman unless he thought it would be welcomed. Do not forget that the phone messages are not the whole story. You have not heard the contents of the phone calls, what was said in person, or the body language and other signals that were exchanged.
