Does he see that he is making a choice to not work on the M?
I don't think that my husband sees that him consistently choosing sleep is choosing to not work on our marriage. He sees it in much more practical terms--sleeping so that he can go to work the next day and provide for us, etc.
Would he agree to scheduling in time, just for you?
I can't say that my husband is gangbusters about it..he has crapped out 2 nights out of 3, but he keeps insisting that he is in the process of building a new habit and to please be patient with him. For the time being, I'm doing that. Would your H agree to build in CorriTime into his schedule?
