His Addictive Voice is stronger than his better nature right now. It won't let him volunteer for anything that threatens it. He's in the clutches of denial and blame-shifting -- his only hope is that things get bad enough that he has to find the fight within himself.
I'm just sorry you're in the middle of it! I know you have a lot of logistical reasons for living there, I just hope you are working on your exit strategy as soon as it's possible! In the meantime, I'm sending strength (and loads of patience) your way!
