Personally I wouldn't buy into the idea of an endgame. If at some point you reconcile the marriage, you still need to apply what you have learned. And if you don't, you're working on being a better person for/in the next relationship. I think it is constantly in motion. That being said, I am pretty sure I am heading for the "endgame" of my personal journey this evening. One way or another I'll let you know.
