I will keep checking back -- and advising -- as long as you are ACTING on this advice. Not MY advice (you need to consider EVERYONE's, on all sides, and formulate your own plan) -- but acting, PERIOD.
You are obviously an introspective guy. A writer. A planner. You are a LOT like me.
What I had to learn was, in DBing, it's all about ACTIONS, not WORDS. There's nothing you can write -- or say -- that's going to bring your wife back.
