Good stuff Jen... a good outcome for all concerned. Now you need to start looking at getting him to attend the PTSD course, which all the details are contained within the
PTSD National Courses announcement. Vet Affairs cover the cost, and he will be a knew man after learning everything there is to know about the ins and outs of PTSD and living with it.
Saying that though, he must also be stable enough to do it, ie. alcohol and substance use under control, etc etc. Do it... you won't regret it.
