Will she ever love me like she used to?

I've been talking to this girl for about 5 months. We're both juniors in high school, birthdays are four days apart lol. She isn't very smart and spends a lot of time studying every day. She puts so much heart in her school work that I notice she'd rather do her homework than talk to me. She has always been the one to start conversations whether its on Facebook or text. Every time I wold log on to Facebook I would receive an IM within 5 seconds, and every day we would text for hours. I sometimes ignored her, unappreciatively, because we would talk too often. We live pretty far from each other so we only see each other on Skype. Then all of a sudden she stopped texting and messaging me on Facebook. We used to Skype once a week because that's when her parents would be out( her parents don't know about me, and probably would get mad if they knew about me), but now for SOME understandable reasons we haven't Skyped as much, around once every 2-3 weeks. I'm pretty close to her siblings too, which made me feel like a family friend. But, about a week ago, which is about 1 and a half months after she stopped giving me all that attention, she asked ME to be her boyfriend. Dazed and confused that she even had those feelings for me (she's not much of a flirt); I said yes, even though i didn't think a long distance relationship would last. For that week nothing really changed between us, besides the fact that we were talking about going to college together. So the night before yesterday she told me that we should just stay friends. I felt like I got stabbed in the throat. I was so sad that I didn't eat for 36 hours. I was completely heartbroken, not because i wanted to be in a relationship with her right now, but that I was scared that we would never see each other and start a real relationship where we would actually see each other every day in the future. So the day after the heartbreak, I messaged her on Facebook three times throughout the day, knowing she he had her head buried in her books for the SAT the next day. She ignored me every single time :(. So I'm asking, will it ever be the same between us will we ever be as close as we were before? Does the fact that she doesn't text me anymore mean that she isn't interested? Should I make my self "less available" (by telling her I'm busy and not logging on to Facebook) to make her miss me? What are some strategies to get her to want to talk to me more? Also, I noticed that she would always find a way to talk to me when she really wanted to. Please help, I desperately miss her obsession with me and the missed calls text messages every Friday night asking me to get on Skype. I now truly feel you never know what you have until you lose it.
