I think it is perfectly normal for you to feel this way. I was deployed for 7 months, but we didn't have "problems" during that time - none that I was aware of, but of course that was a misgiven conception. I see now that we did, and it led to my W's affair.
Since he is gone for a year, this would be the time to be GAL - I need to follow my own advice. I was in the military for 6 years. I am here if you need to talk. I have seen it all while I was in.
