I think there is only one way that you can do this. Is by talking and talking and talking till he gets it. That is what some of us have had to do to start getting what we needed. You may need to point out exactly what he is doing. I know that i'm guilty of this behavior with my wife some times. When she actually calls me on it I am able to start noticing the things that I do that cause these kind of things to continue. So I would say just call him on it.
