Ashamedof, Listen to your inner voice that wants sobriety from the opiates, and detach from him whenever necessary.
If he's ranting go to another room. Or go to a meeting.
Don't let yourself get pulled into any arguments.
Baby that sobriety, it's 5 days old and I want to hear it makes it to 5 months, and 5 years.
One thing at a time here...right now simply guard that sobriety with your life, every minute of everyday.
You don't have to tackle his issues. Simply guard that sobriety. Don't take on too much at once is what I am trying to say!
Can you go find a serene place when he's on his nightly binge? A good book? A wonderful movie? Or chat here? Anything to not let it affect you.
