OH went away for 4 months last year and is about to go away for another 4 months (in a submarine).
Thing is we seem to argue a lot before we have a long separation - is this normal? Does anyone else notice this? 
I think I get over sensitive and anxious and he seems to become less understanding and tougher with me. We live 500 miles apart and have lots of kids all over the country
so life is usually pretty hectic and all our time together is snatched, and often involves catering for a large family.
