I am strongly in favor of exposure in almost every instance. You DAMNED sure shouldn't LIE to cover up their affairs, but I also think you should proactively expose them to a very tight circle of supportive friends and family who you feel will support your marriage and exert some influence.
Affairs thrive on secrecy and intrigue. Break that, and you're already halfway home.
They WILL be livid when you do this, but they're already cheating on you -- how much more can they hurt you?
