Well, I'd keep in mind that he is an "A" and they tell half truths at best. You have no idea what really happened. You are jumping in with both feet by just listening to his words, and ignoring his actions.
My idea is for him to find his own way, he is an adult and this is his problem to solve.
How about your going to some meetings, you work on your end, while, if he decides to, he works on his end.
