I am glad your H managed to realize for himself that the communication issue was HIS problem to resolve, not yours.
I do think staying dim will continue to help you. Let him initiate most of the contact (I am doing terrible at this myself today, so do what I say and not what I do)... it seems like that strategy has been really effective. And if it works, keep working it.
