I guess what I mean is that they do not work with him in any way to help make the PTSD better. I know it's not easy, and sometimes feels impossible, but I also know there are activities and thought processes, etc, that can help. Instead of complacently accepting the role of the victim.
I often suggest he go more often to his counselor, and that's the only reason he goes at all, even sporadically.
He is able to function, he works full time, and he goes to board game nights with friends once or twice a week. He can summon the ability to do the things he wants to do. He just has no sense of responsibility for doing the "boring" job of adulting--being a husband, father, homeowner, pet owner, etc. And at those times, he plays the PTSD card.
