Drained,
You are doing what you need to do for you right now. You are stronger than you think. Please go to face to face meetings, and don't forget I am here if you ever need someone to talk to. Just pick up the phone and call. I will pray that this is his time to get clean, are you addicted to him, maybe. We all seem to be addicted to our addict since we love who they use to be.
All of us here care about you and want you to keep posting, we are here to give you support when you need it or for you to give us some when we need it. Hopefully you can post positive things, but if it does not work out don't worry about it, many people here, have been through the same thing many times and know how you are feeling.
Hugs coming to you
