Leslie, I think you are on the right track! Detach, and GAL! It worked for me, anyway. Find something that makes you happy, and don't allow his confusion and choices effect your life. You control you, and you cannot control him. Be the boss of your life, and perhaps let him know that you are moving on, with or without him. Which doesn't mean that you leave him, physically. You could make him aware that the door is open to reconciliation, but you are not sure how long you will keep it open. Set yourself some goals, like join a club, take up a new skill, take kids for a walk twice a week. Or, even, small goals, like buy a new perfume, change hairstyle, smile more often, don't allow H to push your buttons, etc.
Oh, and try and avoid R talks, unless he brings it up. And, then just listen, and restate what your intentions are.
Good luck! Hope it works out for you.
