Although it definitely would not be considered good DBing, I think that if I saw those notes just "stuck" in the side of his briefcase, I would find an opportune time to pull them out and look over them quickly to see if there was anything added (or put in that pocket with it ...) Maybe if there was anything added or attached to it, it might shed some more light on what he is thinking/working on?
Also ... do you think that if something like this was related to H and your relationship, that he would leave those notes anywhere you might possibly see them? I'm wondering if this might not have as much to do about you as you may be thinking...?
Just a few of my thoughts.
Stay strong Deb. I want to echo the sentiments that others have here, in that I think that you are continuing to do awesome ... despite all of the craziness going on around you!
