She should do what she wants to do, and you create as much stability and support as you can. There will be times that her education and career are her source of support and routine, her own identity, and allow her choices important for you as a couple. For officers (esp. the higher up you go) there is much less spousal connection and support, so having her own identity and community is important. Its about both goals being in focus, flexibility between you as much as possible, and knowing that some separation is going to happen and will be OK. FWIW- I am an officer's wife and have my own PhD. Can't tell you how important keeping faithful to my own aspirations and having a day-to-day life that doesn't hinge on the army has kept the negative aspects of the army at bay. Yes- I've had to be flexible (and thankfully my career is pretty "moveable") but its kept our whole life in perspective- he has his thing, I have mine. We make it work. If Hood is where you are going, if I were her I'd reduce my "stuff" to absolutely the lightest amount of junk you have and get a short term lease on an apartment and get going. If its a masters, it should be 2 fairly quick years. And many schools have some flexible options for a semester or so (on-line courses, independent study, and if the masters has a research or practical component, that can also often be done from a distance or without regular hours depending on the subject) so that can weather a few months of change. Also, even masters programs will often take transfer credit. So, if she did a semester at A&M and your station got changed, if she isn't too far in she could likely transfer that credit into another program. As long as there is a willingness to be flexible to put the pieces together and your marriage is at a point where separation is lousy but you're not freaking out over a few months, have her figure out what is "first best" for her and then what back-up, Plan B you could have.
