@Paggos,
Well, one thing is you have to do what you feel you need to do. Being so young, it is nearly impossible for you to have a closer relationship than over the phone or over the internet. In my own experience, long distance relationships don't work out at all, they are just impractical. That you are able to stay on the phone with her more than ten minutes is a miracle to me. Phones don't cut it with me.
The main thing is, you have to make your feelings and intentions known to her. How else will she be aware of how you really feel and how will you ever be able carry on a legitimate relationship with her if nothing is said about that. One thing I can say though is that around her age group, attention in particular is something she may crave, and your being a part of that fulfills her requirements. That does not equate to any form of love aside from her own self love. So it has to be made clear and present that you like her and those feelings are returned? otherwise you are just wasting your time.
But I would also point out that you yourself may suffer from the same complex that you put on her and her feelings for her current boyfriend? infatuation. Infatuation wears off after a while, leaving the true feelings and cultivated relationship to take over. If you care about her as a person, then you have a definite positive.
As for waiting and hoping the relationship will come to life, I can say that waiting is passive and to be passive to have things done to you and a negative. It is a widely help belief in the arena of philosophy that what is good and best is active. Even in Plato, in the analogy of love wherein the horses (representing aspects of love) drawn chariot pulled who struggles to bring them both together, you better believe that a flying chariot pulled by two crazy horses and a manic charioteer is active. LOL. Hope is sometimes a good thing, unless it is a false hope. But I this kind of hope also translates with a bleeding heart. You know what they say about a bleeding heart, a bleeding heart only leads to blood loss.
On a side note, sympathize with your current situation? been there, done that. I've been in a relationship now for 7 years and I can say the time before and during our forming a relationship was arduous to say the least. Don't want to go there again, so good luck.
