I can't begin to tell you how much I respect you Cat. We all need to vent, and PMS definitely tends to make things *feel* so much worse. Blech. Your fears and needs are valid.
I think what LN said ("Let him know there is nothing to fix. He's off the hook. You're OK.") might be a good thing to consider sliding across the table to H. He knows what you want and need and feels helpless to act...so maybe if there's a way you can take the pressure off him it will help (please know that I think you deserve the happy movie ending NOW, but it's probably not going to just show up, grrr). I wish it didn't mean that you have to plug on with all this weight on your shoulders. And it pretty much sucks that he doesn't appear to be getting anywhere with all the space he's already been given.
