I agree with the others. First and foremost, go to YOUR meetings, they will help you. Second & just as important....Boundaries.....what you will or will not accept while he is living in your home. "Say what you mean, Mean what you say and say it nice."
Your AS learned in rehab what he needs to do for his recovery, and it is HIS recovery. You can't work it for him, you can't love him clean. However, you CAN work on your own recovery.
Remember the 3 c's
You didn't cause it
You can't control it
You can't cure it
