Hello Andrea,
My husband and I have been married 11 years, and May will be 11 years in the Army for him. He is currently on his second deployment. Everyone here has given you great advice. Loud noises, playing jokes such as jumping out at them, crowds, and sleeping are all problems that a soldier can have. After my husband came back from Bosnia and ever since then, a certain perfume makes him sick to his stomach, sometimes to the extreme of vomiting. All because the mass graves were doused in the same smell. When he was home on R&R a month ago from Astan crowds bothered him more and he had a problem of sleeping. He felt very out of place the first few days, like he didn't know "what to do". You have to think of how he sees things now. You have changed physically, possibly personality also. The house he remembers has changed, people have different material things, look different. TV is different, shows, movies, etc. Smells are sometimes different to them also. I mean gees an MRE packet of peanut butter doesn't quite taste or smell like JIF HAHA Just take your time with him, talk and most of all listen. If he wants to go and hang out with the guys alot soon after just realize hes doing it because they are his family, his brothers. He trusted no one else but them. He may be very cuddly or he may distance himself, its different everyday sometimes. His attitude may be different. Where he may used to talk to you about something that bothered him may now make him more furious. Someone said don't make plans without him....good idea. Maybe you mention things, let him say yes or no but if you get to that place and he doesn't feel comfortable, understand and be willing to leave no questions asked.
Okay so Im just rambling on. If you have any more questions feel free to PM me anytime.
Good luck to you, Angela
