Long Distance Relationship: Me and my Girlfriend are both 15.?

And i Just found out that my aunt is getting sipped off to the war in iraq. I currently live in Savannah, Georgia but in january I will have to go back to anniston, Alabama. Me and My GF are deeply in love and I know this is the person I will marry. But her parents dont want her dating until she is 16 (on dec. 31 2009). My other aunt tells me she would bring me up here from alabama which is only a 5 hour trip. I really want to stay with thiss girl because i love her. Do any of you have tips and ideas that I can use to keep my girl. And so that we dont lose trust in each other. Please and no negative answers please.
