The best thing my therapist ever told me wheile I was going through this mess was, "Why does every conversation or interaction with your wife have to be either a positive or negative contribution to the chances of you getting back together?"
At one point I even kept a scorecard: positive, negative, or neutral (+/0/-) on a daily basis.
What a newb I was!!!!
Everybody hurts. It's part of life. Don't miss the good stuff.
