Thanks all for your replies. I left a lot out but in the scheme of things, they dont matter. What I mean by "healthy" is that he was not slurring, he wasnt angry. He said he was happy. I didnt mean that I knew he was healthy. Some of y'all are so literal.
I want to drill it into my head that he is never going to be the person I want him to be. I dont consider smoking pot a bad thing, but I guess it is if youre an alcoholic/addict. Your comments help me to see a different side of things.
This has been hard but I wont give in and see him, not for a while at least.
