First thing... get HIM to read the book, then discuss it with him. REALLY discuss it. See if you can get him to open up. Find out what is going on inside his head. See if he is willing to work on it with you. I bet if he reads the book, he'll start to get a better idea of just how important this is to you.
Next thing... get him to log on here and read this forum. When he sees the pain and anguish expressed here, maybe that will turn him around.
