Morning and welcome to the SR family, this is a very hard one, my AH was also sober for 8 years then relapsed. Tell you the truth i never said anything to him, as i wasnt sure and he was doing it all secretly, but, i have learnt since being here, that we cant really do alot, except look after ourselves and be there for them, only they can deal with it. Please read all the stickies they are very useful. Remember the 3 c's.
You CAN"T control this
You didnt CAUSE this
You can't CURE this
others will be along shortly and im sure they will provide you with a wealth of good information. Keep reading and keep posting (((HUGS)))
