Hi Bella,
I don't mean this to 'dampen your spirits' at all, and I do not know if the same wil happen for you or not but I will tell you my story...
Alex found out he had PTSD just before we got together and we did the ptsd course together... during that time I tried to tell all of our family and friends what was going on and how certain things can affect him and so on... basically they thought I was just making excuses for him and that he had told me all of this to make me feel sorry for him... Even today certain members of his family don't want to hear anything about the ptsd and what it creates...
I do hope your info sheet does better for you than my 'lectures' did for me though...
Good luck with everything; I hope you will have him beside you for Christmas and that his mother takes our advice...
Tammy
