I had a huge long post written but I deleted all of it.

This is all I really have.

Are you happy with the status quo? (this includes sex, but is more than that to include the way she treats you, and how her outlook on life affects you)

If you are not happy, do you demand she does change in order to continue the relationship, or are you willing to accept your unhappiness and frustration?

if you do expect change on her part how long are you willing to wait till you throw in the towel?
