What is the two of yours understanding re: "dating" now that you consider yourselves "separated?" (although living in the same house) Was there any agreement reached?
If you agreed that you would each remain faithful during this period, I would have a different kind of advice than if you didn't, or if there's really just sort of a "fuzzy" understanding in place.
WHATEVER you do, do NOT reveal the source of your intel! Ever. Ever. It is a valuable source of information for you as you go forward, whether it's cues on how you can improve yourself and re-attract your wife or whether it's getting a heads-up on any legal or financial threats that could damage your family. There is much power in her NOT knowing what you know and what you don't know, or how you know it (more on that later).
