Entirely possible. Trying not to read too much into it.
But what's the play? If they want to be happy and appease just to get D finalized it seems like there's nothing that can really be done. Sometimes DB really seems a lot like a wing and a prayer.
Detach, fix yourself, and hope that W sees the change and decides to change course. But from the sounds of it, most of the time this doesn't happen and maybe it's more dumb luck. In the end you come through with change to yourself but that's like getting a consolation prize, tbh. "You're now single again and your kids will grow up in a broken home, but at least you feel better about yourself!"
Not trying to be negative, just realistic. Life isn't all unicorns and rainbows.
REPOSTING THIS RESPONSE IN CASE YOU MISSED IT
So you are looking to do something that will GUARANTEE your W stays with you? Good luck.
What DBing does is increase the chance that she will reverse course and come back to the MR. But yes you are right, it is just hope, there is no guarantee. I don't know what the percentage but I can tell you that the percentage of LBSs that move to R through pursuit, pressure, and the like is minuscule. Probably in the single digits at best.
DBing, done right, increases the odds your WAS will come around. But even that is just a chance, not a guarantee. The only thing guaranteed in this life are death and taxes. Not necessarily in that order.
