kikidee, I would advise against laying down that ultimatum. If you don't want to continue doing what you can to save the M - that's your decision, and you do what you gotta do.
But to expect your H to drop the OW and recommit at this point? I'm sorry, that seems pretty unrealistic right now.
Remember, focus on the things you can control - your PMA, how you react, how you conduct yourself, your GALing - and let go of the things you can't control - such as your H's actions.
Your sitch seems to be hurtling along at a pretty fast pace. Do what you can to slow things down, rather than cranking them up another notch. Time and patience are two of your best friends as you DB.
