Sorry to see this is where you are now. Not the step I would take, but then I'm not exactly in your shoes either, so I'm not going to swing any 2x4's. I do think H deserves the courtesy of you letting him know you are stepping out on him, if for nothing else than to protect himself. I gather he's oblivious to your immediate plans? Most of all take care of yourself, and be very very careful, the minefield you are intentionally stepping into is very difficult to get out of unscathed.
