You sounds like a very sweet person. The thing with speed is it NEVER gets better. It just gets worse and worse until you end up in jail, a mental institution or dead. And he will take you with him - even if you aren't using.
Start working your own program at alanon - really work the steps with a sponsor - and let him work his half-assed fake program at AA while he's high. See who gets spiritually fit first.
Or you could just try church. Maybe you'll meet a nice, spiritually fit guy who doesn't use speed.
