Well, when I saw the title the word that came to mind is DETACH! How is a different trick altogether, of course. It sounds to me like you are on the right track, as far as he is concerned.
I think the real key is to get on the right track as far as you are concerned. Move the focus from what you do with respect to him to what you are doing for you. GAL. Don't let it kill you that he doesn't want to tell you anything, as long as that's happening you haven't detached.
Right now it isn't important (in my opinion) if he is noticing anything. You need to take care of yourself, the important person to notice is you!
When I have a chance I will read you other posts, and see if I have any other ideas.
