Well, look at the bright side: at least your "gut" is still working correctly.
As I told you yesterday, there's a reason why they tell you NOT to let these "closure"/goodbye phone calls or meetings happen, under ANY circumstances. Or, as someone very wise put it more succinctly:
"If you let them, the infidels idea of closure would be a cruise together, or one last f&$#. It doesn't work that way."
Your "fumble" analogy is a good attitude to take. In a football game, one fumble RARELY costs you the game. However, going "+3" on turnovers gives you over a 90% success rate, and conversely, going "-3" means you'll lose the game over 90% of the time.
Chin up -- not only does "-1" not cost you the game, I'll bet your wayward wife blew at LEAST one thing yesterday herself, so you're really at "even" on the "turnover" battle.
It's all about how you get back up on your horse and RESPOND now. Lovingly lead your wife, and shine a path back toward your marriage with your GAL stuff. Look good, smell good, and lead her thru a bullet-proof withdrawal period. She won't forget your efforts, I promise you.
