BH, I think you are right, and I also think the odds of it happening depend on the betrayed spouse being able to step back, take a good look at things, accept responsibility for their part, and set realistic expectations for the other partner. In short, all the stuff that the popular culture does not encourage.

So, while the odds are not good in general, I think DBing can raise the odds. how much? Hmmmmm... Realistically... judging from the ratios on the forum.... not that much!
