Wondering..

Does any one else have a SO in the military, or is a fire fighter? Everyone has always said that I have the perfect person. My fiancé is in the military and is gone every so often.. He leaves on our due date for about a month. On top of everything he is a volunteer fire fighter and is always leaving in the middle of the night or when he gets home from his other job. He is an interior fire fight which makes me worry 100 times more that he runs into burning buildings. Maybe I'm over reacting and being selfish but lately I'm feeling really alone that he is always gone or leaving..
