Okay Nick I hope this will help you decide,
I think you shouldn't go see her because obviously you have strong feelings and don't want "fun without any of the other stuff". It sounds to me from your story that she did/does care about you, but just as you feel that pain at being away from her, she does too. You are both in the military and hence will be away from each other for very long times, and it will probably not be possible to have a relationship of any value while you still are in the military. Sorry to say it but you need to hear that. She may have come to that conclusion too, and doesn't want to hurt herself and you anymore. Only at the same place for 6 weeks? That is not very long. Think how much more that will hurt if you get together and start going out, just to have it ripped away from you. What is this moment of stupidity you speak of? I haven't seen it, you were both in love but your desires of careers took you both somewhere where relationships are very hard. I have had a long distance relationship and they are horrible. This would have continued unless you both married. I think you did the right thing by breaking it off way back. It did hurt, and will continue to hurt but you need to move through it. It would not have been any better if you kept going out. Would it have been any different if you were still going out but never saw each other? not really. If you both still want to be in the military for a while I don't think a relationship between both of you will be possible. So after my long winded speel I say this. Don't go see her, it will only hurt you more. Tell her why you can't and be honest. I hope this has help you through. Good luck Nick in a tough spot man.
