so - he got drunk, intentionally got behind the wheel of a car, got pulled over, blew a .13 and got arrested.
so far outside of some time in jail, what CONSEQUENCES has he had to endure?
YOU paid his bail
YOU called his job and made up an excuse.
YOU tell him to go to meetings and even hold his little hand to make sure he goes.
HE IS STILL DRINKING.
if it was your recovery, i'd say you are doing a great job...but it's not. you can't do this FOR him. you mentioned training wheels...it doesn't work like that.....
WHAT IF instead you step back and let HIM handle this? or at least observe if he has any intention of doing so. you aren't making getting sober EASIER, you are enabling him to keep drinking.
