I'm a militaire in the US Army…

I really want to go back home, to my future wife and our kids. But because the mission isn't done yet we have to pay for our own ticket back home. So I'm searching some money so that I can surprise finally after 6 months my wife and kids, back together forever. 

It's not possible to ask money at my fiancée, cause she has no more money left to spend extra… I need to go home to take care of her and our kids. Please, someone who wants to help me (and my family)??
