Mojo, I don't have time to do justice to your question at the moment, and I want to. I'll think about it and get back to you.
P.S. The key to the 5 is information/knowledge. The 5 is the scientist. It's the 7 that is afflicted with gluttony and greed. The 7 wants it all and cannot get off dead center because that means eliminating some options.
But just let me say that abandoning trying to "please" your H is an excellent plan. Not with a grudging "no one can please you anyway" attitude, but in a gracious, "pleasing you is YOUR work, not mine." This will liberate you tremendously.
