Well, I am glad to hear he was up front with you from the start. PTSD is hard enough, never mind being further confused by an inadequate system.

Your husband is right and it's good that he is being supportive even though "yes" when a trigger takes place often it is getting through it an hour at a time to a moment at a time.
Oh, I have been there so I know how hard it can be. I think it's great that you stood up for yourself. You do that for others too you know, others who are too afraid, but also deserve the support when they are really struggling. PTSD can be crippling, it takes time to gain on it, lots of patience and support is a "must have".
