Hey Bird,
Tell him from a former OTR truck driver to another, lighten up!
I used to drive from NC to various locations in NYC twice a week. Then got into a bad crash and after years of this monster I'm in a wheelchair due to full body CRPS along with complications of my cerebellum shrinking. I can see both sides of this, and if he thinks it over, he's got the better end.
All he's got to do is to continue doing what he chooses to do while you are learning to deal with life in a different way. It may seem that's it all about you at times because it is.
He doesn't hurt when he moves. He doesn't look at life as a physical struggle.
My wife, who is also my care giver, reads some of these posts about how families get stressed out and tells me she can understand both sides but is happy that we have been able to balance things.
Excuse me for saying this but if I were you I'd tell him "This ain't no truck stop, get it yourself "... lol
(I hope he reads this...)
Be well...
