Why is she mad at me for i did what i did for both of us?

Eh, she's probably upset with you because she's feeling very overwhelmed from being pregnant. It's tough for anyone to be a spouse to someone in the military, trust me I know firsthand. My son's father couldn't handle me being in the military and my last deployment totally killed our relationship. It's very important that you have someone by your side who understands and actually SUPPORTS your commitment and obligation to your country. You also have to remember though that you are not the only one to be making these decisions. You now have a family, soon to be wife and child so for you to just volunteer without consulting with your partner was very wrong of you. It's one thing to be ordered to deploy and another to VOLUNTEER. You were a bit selfish in that and only thinking of yourself. I know you said it was because of money but there are other ways to make money besides deployments. Also, your tours overseas aren't that long either are they? I know the ours are 1yr I thought the AF was 4-6 months? Unless they changed it..anyways, from now on I'd try and include your fiance in big decisions such as the one you made. Good luck on your deployment and hopefully everything works itself out.
