JJ, Good strategic 1st strike. You better beleive your W will find out about it. Not sure you should be the one to do that. When she does find out, her reaction will say alot about how much progress has been made in your R and just how detatched she is from the dirt ball.
Keep in mind that it may piss W off bigtime. Make sure she understands that this is between you and OM if she pursues you in anger.
