In the most simplistic terms, DB is about showing your spouse that you'll be just fine without them (GAL, focus on yourself etc.). Most of us are so riddled with fear of letting go that we cling to the spouse until we get so disgusted with the situation that we finally let go. In my opinion, the faster you can get to letting go, the higher the probability of reconciliation. Again, that's my opinion, it's not necessarily fact.
