First off, it's not a competition between you and the OP. It's more about you and your WAS.

Then, life is complex. What works in one situation may not work in another, or what we think may work, may not work. We can only try, and monitor for results. So, does going dark prompt "out of sight is out of mind" or does it prompt "absence makes the heart grow fonder"? Only the results in your sitch will tell.

Does the WAS bonding more with the OP increase the chances of their union being successful or does it open the door to their union dissolving? Well, there, I tend to think it helps dissolve things, in time, just like with most relationships.
