Just a reminder - Nothing changes, if nothing changes.
Right now, I would be so scared about his health and it would be hard not to enable him and have sympathy. What do you think would happen if you left him in the hospital and allowed him to feel the consequences of his actions...alone!!
It's during these times of clarity, that can help him. But the want must come from within him. His brain is most likely SCREAMING for his DOC and the more he lies to you, the more his brain is working to protect and sustain his addiction.
Unfortunately, most of us are not drug counselors and yet we try to continue to act like we are. We are not qualified and refuse to see that. Please try not to "council" him about his addiction anymore then you would advise the Doctors how to treat his heart. It's just not our area of expertise.
My prayers are with you both!
