Hang in there, pray for the strength to endure, God will answer your prayers. Remember the Purpose Driven Life, remember the blessings God has instore for us!!
If he is starting to detox, it will be impossible to get along with him in a "normal" conversation. He will say alot of things out of fear and frustration. (When my W was detoxing she was rude, selfish and moody.)
They will do almost anything to get their drug of choice. So if you stop one source he may find another, my wife was driving a car-less drug dealer and his GF to crack houses in Houston to get her hydrocodone. I was totally unaware of the amount of perscription drugs that could be purchased on the street. The "big" dealers get them from fraudulent doctors, shady pharmacist and foreign sources.
I know it is hard to figure out what to do when someone you love is endangering themselves. We do have to put it in Gods hands. We can try to control the sit., but we will most likely end up bitter and frustated. Trying to control someone is against DBing and against Alanon. Plus God wants us to give control to him. If we should trust anyones promise we should trust the Almighty.
Should you get on with your life? Yes, do all the GAL you can handle. You will be happier and better off in the long run. I am not saying your H is hopeless, nor am I saying give up on him, but I am saying don't let him hold you back from what you want. (Example if he feels that because you move into a new place you are moving on without him, so be it.) Pray, DB, GAL and remember you are here for a purpose, you are not an accident. By doing these things you will be prepared to handle your H when he finally gets clean. The first year he is clean, you know his thinking is going to be messed up.
Of course I don't know what God's plans are for you and your H. Maybe God is preparing you, the stronger person right now, to handle your H after he goes to rehab.
Sam, Thanks for posting on my thread, you have helped me so much, I just hope something I have said will help you feel better. I can really relate to your pain.
