As for the A? Well, I wouldn't expect any movement on his part unless you push the issue. Ask him for a date; if the date is not acceptable to you, you could choose to move out yourself and either have him buy you out or insist on selling the house.
Walking away and refusing to engage in a difficult discussion (especially when sober) seems pretty typical. Unfortunately.
