I understand your concerns, and I really understand your need to plan. The problem you are running into is that he can't plan right now. That's his problem, but it is turning into your problem! I think that the best way for you to handle it, and maintain your sanity, would be to really forcus on the things that you don't need him for right now. If you can resolve some of those, there at least won't be as much uncertainty ahead. Then you can see if you can get small, incremental steps out of him, so taht you can continue to more forward.
I know that doesn't get you where you want to be, when you want to be there, but it might be the best you can do. I really understand your apprehension at what lies ahead, and that you have decisions that you'll need to make, and you need his real input to make them. Just try to keep breathing, and move slowly and steadily, I think it is the only way!
