When I read your update earlier, my first thought was that you and W are living as "roommates" passing each other. You two are not living as a married couple.
Toots raised a very valid point: What do you REALLY want out of life?
Again, you have your destiny in your own hands and isn't directly tied to W. Really contemplate on what you truly want and so richly deserve.
It seems to me that your W has you in a place where she derives "some" benefits from you as her H without "the whole enchilada."
I cannot imagine being married to someone WITHOUT any form of emotional and sexual intimacy. I have plenty of friends and people who would make ideal roommates out there.
