Welcome joinedintime,
First off, congrats on 6 months sobriety... that is awesome..
Just like you, your friend has to be the one that stops drinking and make the decision to change his life...
You can be there to support him in recovery but not his addiction.. I know it's sad to watch someone you care about destroy themselves with an addiction but if you are not careful their addiction can destroy you in the process..
It's bad. He's bad. He knows it. But doesn't want to change
I think you said it best yourself... he doesn't want to change..and until he does there is nothing anyone can do to help him..
I know you are a recovering A but have you thought about attending some alanon meetings as well? You will gain a lot of insight there in how to help yourself detatch from your friends problems and to put the focus back on yourself and your sobriety...
Sometimes the best thing we can do for our addicts is to let them fall..
