And pup I would add that QS should expose to anyone on OM's end he can as well.. you said he was in the military QS, if there's any leverage there I would use that too... that way you hit the affair from both ends...
And note : Hit the guy's leverage... NO WARNING.. NEVER WARN OP you are going to bring consequences down on them... the wife yes, you wait til she wants LEAST to hear them and then you hit her with them... as she's leaving for her plane flight etc... you send her the note ... BTW, when you get back I won't be there.. etc... and you won't get a $ from me etc...
That's the LAST thing she wants to see when she heads out the door full of confidence that she's fooled you and everyone... the last thing she wants to see is that SHE"s the fool and she's also lost her home
