You are doing the best you can for you and by doing so, you are doing the best you can for him as well. Although your calm coping skills may infuriate him, it's not about you really. It's about his own lack of coping skills--that's what is frustrating him. He will learn those skills by watching you and by going to his meetings. If he really wants to change, he will. If he doesn't, there's not a doggone thing you can do about it.
I also meditate and do yoga (as well as go to 2 - 3 meetings per week) and it does help to keep me more balanced.
Keep taking care of you.
