Why oh why

My husband is deployed. This is our first kid. He has papers,signed,itenery,everything ready for him to come home before baby boy is born and all of a sudden they want to pull "we might not let you go home afterall." When they let a guy go home to be with his pregnant wife not even a month ago. When they already have a replacement for my husband. And when I am a high risk pregnancy...ughh I'm trying to be strong,but I really don't want to face the fact that I might have to do this without him...
