Wondering if you should push detox or not? I would say, be supportive, if you can, but as to ultimatums and "pushing", that is not recommended, generally. I wouldn't call and make any arrangements for him either...he needs to do that himself...and if he won't, then maybe he's not done being an active addict and has no plan except to keep bad withdrawing at arm's length. I know this must be hard to face because you care, but it's probably better that you found out about this now.
