Starsky, Yes, Honesty is improtant, but in my sitch I confronted W early on in the EA and it just went deeper underground. If OM fiance knows and confronts him he may deny it and get pushed closer to my W, say yes there is something going on,end it with fiance, and then go after my W pushing their R to a diffent place, or lastly break the A off with W. Could that then harbor feelings between each other since they work together? Could another A between them happen in future? IDK
Wow. That's a lot of what-if's and suppositions.
Or, the OM's fiance could take the information, process it, and figure out what's best for her and her own situation. You know, you're all adults and all that rot.
I don't like the whole "spying" word. Sounds so childish. I think of it as being more "confirming" or "checking."
