I would love to believe that through LOVING actions you could win back the heart of your wife, and enter into a relationship of worship, prayer, and friendship again with her. I don't doubt that it would take time.....but from your orriginal post, it sounds as if maybe you have already washed your hands of the situation.
That made me sad to read that.
Have you ever heard of The Love Dare? Its associated with the movie Fireproof. If you are not familiar, could you take the time to check them out. Pray over the situation and see if you would be willing to love your wife in a completely unselfish way as The Love Dare speaks of...and then maybe she would be open to maybe hear you on quotes she has hung up that your not crazy about, or other such things.
Just some thoughts. Best for you and her as you move forward in this. Blessings!
