To chime in a bit, Sho, I'd like to offer some resources that I think are valuable in the piecing process. Please do check out Dear Peggy website.
They are chock full of information on what happens after the affair. In my mind, they go hand-in-hand with DBing after the spouses reconcile after an A ends. Like Train, I do feel that DBing focuses primarily on busting the affair and outlasting the OM/OW, but does not really lay out the nuts and bolts of reconciliation & recovering from an A.
Bottom line, DBing really DOES saves marriages and YOU. For that, I will always be eternally grateful to MWD for writing the book and being the biggest advocate for marriages.
