Hello, So many people use the term rock bottom. I've been living with 40 year old meth addict for almost 4 years. Nice person when sober but he's been using meth since he was 18 altogether with his own mother. He admits that he has an addiction, he lies, he cheats. My 18 year old daughter moved out of my house because she couldn't stand it. He went to jail for 6 months, lost the custody of his children. I helped to get it back for him, which was not easy. But he is still doing meth and pot . Promises a lot but does so little. Did not he hit rock bottom already? I went above and beyond trying to help him quit but I cannot stand cheating anymore. Should I keep trying or shoul I let him go? I feel like I am wasting my life .
