I am still deeply in love with her and would want her to be the mother of my children because I know she'd do a wonderful job. Even if her hair started to gray out I'd still love her. Here's the thing.. she is overseas... I know.

... either there was a severe miscommunication and you should sit down and talk it out.
... or she is crazy and you should move on.
In the case of the former, being in the military it's a common thing, life is chaotic, your schedule fluctuates unpredictably. Civilian romances are at the mercy of seemingly unreasonable policies. God-forbid you get deployed or assigned out-of-state/overseas, as both of you have to deal with the long distance relationship ordeals.
It's easy to get stressed and for one (or both) partners to get fed up. It happened to my brother when he got married in the Air Force, and I've seen dozens of soldiers face that situation when I was in the Army. Divorces were rampant.
As a drill instructor in AIT once told us, military life tears apart weak relationships and greatly strengthens already strong relationships.
... if she is crazy, maybe you were so busy with your job that you had lower standards, and you didn't notice she had a Doctor Jekyl / Miss Hyde thing going on.
Either way, it's been 6 months since you last spoke. I'd give her some space and just be really casual, keeping conversation light, if you do decide to contact her. If you do decide at one point that she's worth pursuing, you'll have plenty of time to rekindle you relationship...(there's no reason to try and kickstart it on day 1, ya know?)
