You are entirely too focused on the wrong person. You are focusing all your energy on your spouse. (ya ya, I been there done that, it DOES NOT WORK) DBing is focusing your energy on YOU (ya ya, still doing that AND IT IS WORKING).
When you interact with spouse (or your children), tough love works. Project that you are happy with or without her. Treat her like you treat everyone else. And here is the catch - self reflect on how you treat others, make positive changes to the way you treat others.
