Hi I'm a wife of a marine who is suffering from PTSD and there are a few things that i have learned over the last year and a half that he has been back. The best advice i can give to you right now is to be as open as possible with your wife, its not going to be easy on either of you but you have to be open. I'm not sure what your beliefs are but prayer from people at home, church, family and friends will be the best thing right now. I'm not sure when you are going to get home, but when you do the first thing to do is find a counselor that you trust to help you adjust back to the states and life around those you love again. Remember to pay attention to the things that you react to and make those close to you aware of them so they can help try to "protect" you in a way from them. Good luck with everything and thank you for serving our country.
