In talking to a therapist, he said the scenario that plays out more often than not is that the WAS will eventually try to return but it's often too late for the left behind spouse. I'm talking as a general rule in the world at large, not us here in this forum.
He also said that 20% of all divorces end with reconciliation and remarriage. Again, that's the world at large, not just our little corner of it here.
