For the record, exposure -- properly taught (and there is a TON of both research and application of it out there, if one wants to look) is NOT about "shaming" whatsoever. The concept behind exposure is to remove the shroud of secrecy and intrigue that fuels affairs, and to enlist the support of those pro-marriage people whom are close to the cheater in an effort to apply loving pressure to end the affair. Period.
I wasn't going to chime in here, but seeing what is generally considered a very valid infidelity-fighting tool so grossly mischaracterized changed my mind.
That being side, it is NOT taught by DB/DR, and not advocated here, and many of the people who are asking about it (in my opinion) are nowhere NEAR ready to handle it properly, should they decide to do it.
I'd advise to draw the line at "OK, so I won't proactively exposure, but I'm no longer going to lie to cover up his/her affair, either" . . . and leave it at that.
