Nar-Anon Chat™

I have a wonderful caring addict husband that is having a hard time staying clean. We have been going to NA meetings almost every night and still he relapses. I am so confused on how this disease can take control of ones mind even when they don't want to use they still do. I have listened to so many while sitting in the rooms talk about their struggles with years clean. I love my husband dearly and want to believe that he can get better but right now I feel like I should just give up the battle, even it means to let go of 20 years.
I find it hard to talk to anyone about it because they have not walked in my shoes or understand that its a disease and never goes away.
Thanks for letting me type these thoughts.
