This is my take:
If he is waiting for your call, then that is game-playing. If you are waiting for HIS call, then that is part of the same game. If either of you want to speak to each other, then just speak. What's the problem?
True colours are how you behave when there is no pressure to conform from anyone else. If you let him be, you will be seeing where his priorities lie. Could be in drinking, could be in emotional manipulation, could be in recovery, who knows. Until you let him be who he is, then you will never know. Maybe you don't want to know?
