Yes, he has definitely seen a lot. If there is one thing all of us who have loved ones in the military need to realize is that it is unfair to them to expect them to come back from a place where they have seen death face to face, many times barely escaping it themselves and expect them to not be changed by it. They are still the same person at heart, but there are changes, sometimes big changes. It's something that sadly we who have not stood in their boots will not be able to fully understand. And they may never be able to fully explain. The best thing to do is be patient with them, love them and be there for them. Don't push them into talking about things, but if they attempt to..just listen. Sometimes thats what they need, just someone they know really loves them that is there for them no matter what.
I know it's tough, but they have to work through these things on their own terms and all we can do is be by their side.
