The reason nothing happens is because no real action is taken. He is at the point where it goes in one ear and out the other. Real change takes real work. What work do you make him do? You have not given him an ultimatum. My ex said she nagged me. I never heard it. Of course, my mother was the queen of nag, so there was no way I could have. She never said to me, either this changes or I am gone. Maybe, she didn't do it because she was afraid I would do it. It will take much strength on your part. Basically, if you don't do X, then you have to go.
