Could this go far? Please help ! ?

I am a 14-15 year old guy. Having a blast with his girlfriend. I
really am into all this love stuff. Teen love  Mature love. My
relationship so far is going great with her and I am understanding
that later in the relationship we will get in arguments and fights. I
understand also that from those fights we can learn. Well anyways...
To give you a picture in your head of my relationship, it is an
amazing relationship and pretty strong. As a teen I don't really know
about love. But I do know that it consists of caring, sharing and
loving each other. So far that is whats going on. My relationship... I
could say that I have very strong feelings for her. Like never before.
And we did go out before but it was a wreck. Now we are dating again
and it is amazing. What can I say ? I am pretty happy (Some buzzkills
ruin my happiness). I am pretty comited... And I can say that I get
happy to see my girl. My new relationship with her... Well I guess the
break up worked and made us a stronger couple. We talk more and we
share more.

She also tells me that she has also never felt this way... But let me
tell you that it is crazy. When I'm with her I get so exited and happy
and I feel in top of the world. We are at the movies we kiss and hold
hands. We are together we have a lot of fun. But the question (I have
two);

1) Could long Distance Kill this? I mean so far so great... Not good
2) She is only 14 and she says that I am everything she wants in a
guy... So what could that mean?
3) And my emotions are crazy and I do not wanna lose her... What are
possibilities that she could leave me foe another guy after what she
tells me and all the good we go thru?

Note: I am not a player. I am a sweet, fun, caring guy who had his
issues in the past. But got it together and made it happen. Also she
tells me I make her very happy... Could it be possible that we go far
? Like Very far...

Clue: We are 9th graders... I also could use advice to keep her for a
long time... I really like her
