I really like your points (1-6 written yesterday). I think you've thought it all through really wisely.
I agree about not giving your H the letter. I'm sure he knows how you feel well enough to know that you don't want a D. I don't think that there is any crucial bit of information that he is missing. It seems he feels safer when he feels freer. That letter would be pressure.
I can highly recommend Laurie as a coach too. A couple of times I've had a session with a different person when Laurie was away and that worked too. You might want to see if she is available sooner than Jody. I'm sure it wouldn't take her long to get up to speed with your sitch.
Your H definitely sounds as if he enjoys your company. That is huge in itself.
Take care, Tori.
