Hello Nikki,
Welcome to a healing forum! We are so glad you found us! I am a Desert Storm disabled vet with PTSD, and I can agree with Mayhem that my mind is still there in the trauma, reliving it. The first step your husband has to do is to admit he has a problem, which is not the same as a weakness (Marines are never weak) and that he needs help solving this problem. Put it to him this way: He is part of a team, just like he was during the war, but now, the team includes healthcare professionals who are trained to deal with the aftermath of war, and what war naturally does to humanbeings' brains. His mission is to work with his team to solve this problem within his personal life.
I wish I had more time to talk to you now, but I leave for Greece Saturday. I will write more to you when I get back 5 November. I will be thinking about you. The others on the forum will support you too. Right, everybody?
