He says "most affairs end within six months of their seeing the light of day (being revealed to their family and friends)".
I think it's interesting that Harley states the above.
MWD states in DR the same stat and makes no reference to that stat being based on exposure.
In fact, MWD states she is strongly opposed to exposure, even though she does concede it may work in some cases.
And that is really part of the reason for this thread. To examine how some appear to be interpreting DB one way and others appear to be interpreting it other ways.
And from what I can see within DR as well as MWDs articles and letters posted here and elsewhere, MWD both does not condone:
+ exposure of an A
+ attempts to shame, blame, or otherwise coerce an AP to end an A
Rather, her works appear to specifically point at focusing on oneself, to the extent of otherwise ignoring the A and OP, for the purpose of improving oneself and become a better potential spouse, person, parent AND possibly more attractive than the OP.
I know that some truly believe that exposure and direct focus on the A and ending the A works. And as you note Accuray, there are websites out there for people who would like to follow that path.
Whereas here, it truly appears contrary to the premise of DB.
