I have an idea what you're going through. When I lived in AZ I took a job in CO that I thought would be permanent and waited for my kids to finish the school year, sell the house and join me. That turned into six months away from the family. One of us would drive once a month to see the other for a weekend. That was one long time away! In the end the company closed that location and transferred me back to AZ.
A year later, in the Lord's perfect timing, he moved us all at the same time. Our house sold the first day on the market at the same price as we had it listed at for six months the first time.
I can't imagine how hard it is for our servicemen and women to leave young wives and kids for a year or more at a time. They really deserve our prayers because that must be hard, hard, hard on a family. A close relative of mine is an Army chaplain and he tells me that is truly the case, much worse than most people know.
