A month ago I could have busted my divorce but I missed, as it were, the Opportune Moment, because I wasn't listening (back to Square One). But in part that's because I didn't want to hear that I could bust it because the price of doing so was more than I am currently willing to pay.
What I neglected (chose not?) to remember is a key part of DR - busting is about stopping the divorce, not restarting the marriage. That comes later - ideally. I couldn't imagine wanting to be married "under these conditions" -but being married isn't the point. Not being divorced is the point. So I let the Opportune Moment slip past.
So consider the end-state before you send a new play in from the sidelines.
On the other hand, you get to an important - and often-neglected - aspect of the Master Narrative one gets around here, one to which I've referred in my own thread: If it is true that "love is a decision," then we have to recognize that, by symmetry, "not-love" is also a decision. It's binary - if it is appropriate for us to say, a twinge or more of hope in our voices, "Walkaway can decide to love," then we have to acknowledge, much as it might pain us to do so, "Walkaway can also choose not to love (us)."
And if "choosing" to love is a valid outcome, then it stands to reason that choosing not to love is equally valid - if undesirable from Left-Behind's POV. Reality is, after all, that which, when we choose not to believe in it, still doesn't go away.
So perhaps Mrs. T has indeed made a choice. It would be good to know before you order the helmsman to steer the boat beyond the edge of the map to where the dragons are.
