And now for my 2 cents:
Never tell her (100% agreement w/ Maxwell). To do so only makes you feel less guilty. No sense in trashing everyone's life in order to make your guilty conscience go away. Swallow the guilt & move along.
In addition, if you do ever find the need to escape head south. I hear Paraguay has a ratio of 3 women to every 1 man. Not sure about Crossfire technicians, though!
And finally, as proposed, kill this thread el pronto. Women DO live for this kinda detective work. Take it from a guy who's been married for 32 years!!
