Well, 2 things happened over the weekend... I met with the wife for a couple of hours, and told her how i feel and what i was doing. Then I just let her talk and vent, and listened. I managed not to get emotional, just told her i understood her feelings and respected them. She agreed to some counseling, to see if there is anything left to salvage.
And I made it through the first weekend! It was tough, but I did it! 9 days running now...
