Jrock, you seem like you are not really on the fence about this...its seems like you really think exposing is the way to go.
I did read your statement about the blanket exposure, but you seem to have clearly differentiated telling his wife vs. yours and hers family and friends.
So I will ask you this: What's your hesitation? There must be something in the back of your mind that prompted you to ask everyone-what's your concern deep down?
