What ever you decide, know that he probably won’t come off from meth. My best friend started using and I am kind of happy we do not live in the same country. He stays sober for weeks or even months. But then the inevitable happens again. He is probably better off than others, managing his addiction. But his depressions getting worse with every episode. That shit just fucks a brain.
Personally I think it is difficult to leave people who need help. But your relationship might have to change to something different for your own sanity’s sake. He needs to choose to get help, and you need to make sure to take the space you need. I had to learn that by a very hard way.
Good look, to you, and your friend. Just know., he is sick. Not a bad person. But then you can only do limited things to help.
