Sorry I did not read your post correctly. I am sorry that your feeling the way you do. IMHO, I think you are giving him too much power over you. Act as if he is not in a bad mood, etc.. How would you act if you thought the outcome would be good? Treat him like a friend, don't let his actions mess up your PMA.
We all need to vent so keep it coming. There will be brighter days ahead. Maybe, right down all the issues you are having with him and discuss it with him. Tell him how you are FEELING. Follow your gut/spirit.
On a positive note: "Apparently he knew he wasn't going to get anything because he was in on the discussions of who was going to get what, but it still hurt, so he just stood up and resigned in front of everyone."
Him resigning may be great news. Hopefully he will realize that his W and family are more important than this diving club.
