Maybe instead of trying to use law to get her to "submit", you need to earn her respect.
Love earns respect, not trying to force it because it is law.
So instead of demanding that she follow law, love her and lay down your life of pride and demands for respect. In this way, loving her, you earn respect rather than demanding she follow the law.
This is my opinion of what will help. Our Lord loved us first. It wasn't demands that we follow the law that drew us to Him, it was selfless love.
