But I'm not going to take a "I'll stay and work on the marriage because that's my only option" as a response.
That is EXACTLY what I got, and believe me my friend, IT DOES NOT satisfy the soul!
I think you are exactly where you need to be mentally. Able to move on if needed. Able to make it without her if needed. Detached as you can be. You aren't chasing any more. You are your own guy, not dependant on her for happiness. If she comes around GREAT, if not, then you are going to be just fine.
