welcome to S.R.....once an addict always an addict as sad as that is. there is no garantees that he will not relapse again. all we can do is learn to take care of ourself & live in today. his recovery he his. there is nothing you can do to keep him clean. you did not CAUSE it, you can not CONTROL it & you can not CURE it.i hopehe gets clean & stays clean. it is always a sad story when they have been clean that long only to go back to using. keep comng back here & find a meeting to go to. prayers for you both,
