I need to know?

i have known this girl for about three years now. We talked on and off but really didn't speak to one another that often. Since we lost touch and I joined the Air Force I kinda forgot about her. Well just last year I ran into her profile and decided to message her, she was pretty excited. We both agreed to see each other, well I flew back home on leave in California. I am currently in Japan. I came by her house and she was pretty thrilled to see me. We talked for hours, I met her friends and even her family. After I left she was sad to see me go. Well I called her in January and she was telling me after my enlistment was through that she wanted me to marry her, and we pretty much talked about kids and what not. Well its been a few months and we still talk and we are 6,000 miles apart and she is now calling me babe and hun. She is always making sure I take care of myself, and I am startin to have these really genuine feelings for her. Sometimes I can't sleep because of it. is it Love?
