Hi Bill - It doesn't look like you will be losing your wife anytime soon! If she is initiating ML that is an excellent sign!! That you are having fun together and just enjoying each other's company is a fantastic development.
So, what 180's were you doing? Something in her has clicked, and I'm just curious as to when that might have happened. I'm almost convinced it was the time with you on the phone with your sis. I could be wrong, but that seemed to be the starting point, of her saying, "This man has balls," and she looked for other supporting evidence and you clearly stepped up to the plate.
