This guy has constructed his own little world and in this little world of his, things happen as he wants them to happen. Your needs, thoughts, desires are not considered in this world. It is the nature of addictions, and addicted people are very controlling and self-centered. He can't hear you.
You're doing just fine. Don't worry about what HE does or what HE says or how HE reacts. Keep the focus on YOU. It feels weird because it is weird. Changing one's habits and reorganizing one's universe is disorienting. There's no way through it but just going through it. I finally realize this is what "one day at a time" means.
Is there any other living arrangement that can be made during this time? It might be easier on you to make a clean break versus trying to continue to live together with a house on the market hanging between you. As much as I HATE the idea of living again with Mommy at my age - it was far more beneficial to my sanity to get away for a while.
