As I see it, at present you know this girl, you like her, she knows that you like her, but doesn't seem to be encouraging a relationship.
However, she is willing to accept friendship.
So be friendly.
And who knows?
The friendship may even blossom into something else.
The best relationships are, I think, also the best friendships.
But she really may not want more that to be just friendly - and, if this is the case, then you must accept it, because a relationship has to be a two-way thing for it to be successful.
You really would not be happy with her ~ no matter how attractive you found her ~ if she were not as interested in you, as you were in her.
But no-one can have too many friends ~ and, as I said, you never know where friendship may lead
Good luck
