I say this with the utmost loving kindness...
It doesn't matter WHAT the addict is thinking. You will never, ever, ever, ever, ever, ever understand what goes on in their heads (unless you are an addict yourself) and as someone who has no experience with addiction, even the most thorough and heartfelt explanations or descriptions of what it's like to be an addict will baffle you. It's senseless to those of us who don't have a drinking/drug problem.
Take the focus off him and put it on you. What nice thing(s) have you done for yourself today? How are you working to meet your own needs?
