the best advice for her, and you, is simple: get involved. get involved with your church. get involved with friends. go out and meet people. join the spouses club. just get involved.
if she sits at home just counting the minutes until you come home, then life is going to suck for both of you. granted, when I pulled alert in the missile field, it was only for 24 hours. my wife had a job, and was quite active with the people she worked with. my alerts now are a week long. last summer, they where two weeks long, and 7 hours away. again, she doesn't just sit at home and mope.
as long as your fiancee/wife has something to be involved with while you're gone, then things should be okay.
buying a dog won't hurt, either...
