Hello Sidmom!
Glad you got all the buttons figured out.
When someone is in the grip of an addictive drug, they can indeed seem as strangers to us. All they seem to think about at that point is getting more of the drug. Whether or not he recovers is up to him, and there is no telling if he will get the inspiration, or where it will come from. People do come back from some pretty far gone conditions. But there are also those who never stop.
The only thing you can do is to look out for yourself. You have begun to do that by making him move out and coming here for support! You'll read this a lot here; You didn't cause it, you can't control it and you can't cure it. As tough as it is to accept, his recovery is up to him. Yours is up to you, too!
Once again, welcome!
Hugs,
Smoke
