I don't Understand My Closest Female Friend

Hi All,
Thanks all 4 ur vibrant contributions on this session.
I hav a snag that’s been bothering me 4 a while now.
I hav this friend I got 2 know thr her bros some 7yrs
Ago. In the last 4 years she has become closer to my
Mind than her bros because she is better mannered n more
Sincere than her bros who even tricked me of 10k at
Some point. Her mum knws this n has always preffered
My company with the daughter than the guy bt her
Father will nt hav any guy under the guise of anything
To spent 2mins with the girl.
In the past 2years, no day has past without us talking
Sometimes 2 or 3 tmes. She is always calling n I also
Reciprocate except of course any of us have low
Battery. I love her and she ‘likes’ me too, but
She has repeatedly tld me she has no reason to have a
Boyfriend. Often, her frnds in school accuse her of
Lying about me bt that can't change her position nt even
My subtle efforts.
The truth is I love this girl n ready to treat her as a dear
Frnd ( nt lover). This is actually my idea of frndship
before marriage( sorry if I hurt anybody). from my observations,
This is the kind of frnd she would like to be.
The prob I have now is that ever since we bcam serious frnds
(or close pen pals) she hasn’t visited me. I am always the only
Making all the visits if we must see. Mayb because her father will
Screw her if he finds out she is visiting a guy or because her mum
Has made her to believe that’s better to avoid undue sexual urge.

She doeant seem to  be ready to mak any sacrifice 4 our frndship
beyond her daily calls.
Really, as it is she isnt obliged to me in any way. Thats also obvious
from her attitude except am been in a hurry. At the moment, people
unknwing thinks she is my girlfrnd n she once in a while acts it on phone
or in her house when we meet.
please, i need ur advise. Should stop this talking thing and face my live
expecially now that i'm at the verge of finishing my NYSC or should
i continue to be patient with her in the hope we can develop something better
in the immediate future.
Thanks

For a start Speak2des, how old is this girl, because i get the impression that she is a young school girl.
