I think it's sheer luck to be honest. I can't say I followed DB to a T but I did detach, I'd say I'm pretty over it, and once the rope was dropped, left a little glimmer of light for W to have a path, she never did. Others did all the wrong things and spouses came back. other's left their Wayward after they came back. I truly believe DB gives you something to do. Once you have something to do, you quit focusing and obsessing on the marriage, the spouse. In a way it forces you to look at the person in the mirror, and ultimately that's the gift. You find you, and you save the most important person in that Marriage, yourself.
