Roist - though you say your sitch has not changed that much, I can say I have seen much growth in you.
There is a peace and a calm about you. It resonates when you write that you know in the long run you can see yourself happy w/your wife and happy w/out her.
Keep on trudging forward, marching toward the best possible you!
