Yes, he has consulted a professional. He was diagnosed with PTSD officially, but he doesn’t want therapy sessions. Even if he were officially on the spectrum, he doesn’t feel he needs any treatment for it, since he has been able to make a living all these years. His issues have not disabled him to the point where he couldn’t support himself. And me.

He is also 60 years old. Possibly another reason for his slowness to change.
