One of the things I've learned on this site, is to pay attention to the addict's actions, not the words. Addicts are really good at saying the right things. You can think of that as "quacking." You can picture a duck quacking--they quack a lot, but it doesn't mean anything. What are your AH's actions showing you?? He tells you he wants to change, but what do his actions show? Is he in a recovery program? Is he going to meeting or seeing a counselor/psychiatrist? Is he hanging out with using friends or with sober people?
