It's one person's story, and anecdotally it has as much value as anyone else's success story. But my experience is that such an approach -- especially when tried by a betrayed husband -- serves only to KILL ATTRACTION and RESPECT (and therefore, LOVE, since most women very closely tie their feelings of "love" with their feelings for "respect") from the woman towards the man, but they also totally EMASCULATE the man, and kill his spirit and his self-esteem (and sometimes even to the detriment of his own mental and/or emotional health).
I think Michele's LRT and after-the-LRT are much more within the mainstream of the DB/DR approach when it comes to unrepentant affairs.
