I feel very sad for you, and yet strangely proud. I could "wish" a hundred different ways for your story to "end", but the first would be for your wife to see how lucky she is. No one would ever blame you for walking away. I wonder if the cancer scare, for lack of a better way to put it, doesn't keep you from wanting to leave and possibly ending up alone. Just a thought on my part. But, I can absolutely admire a man who refuses to walk away just because he can. I'm sad, though, that your wife doesn't acknowledge what good man she has by simply remembering your anniversary. Honestly, you seem to have thought of every angle, and are still coming up empty handed. I don't think you've missed much along the way. If posting your story is your way of working out a decision that you can live with, then by all means, work through whatever you need to, please just take care of YOU in the meantime! A walk is a good way to get out to "breathe". No advice, just the wishes.
