Drop her m8 do it.You dont want to just be her friend do ya?!!
I used to hang out wid girls i wanted to fuck and be their m8 thinking one day i could turn them into my gf or some shit.
It never happens like that,do yourself a favour be rid move on find a new girl.
The worst thing in the world is pretending to be m8s with a girl ur desperate to fuck sitting at home jacking off thinking about her while shes of fucking other dudes man.
Its painful man letting go man!! But id rather eat my own foreskin than be friends with a girl id prefer to fuck now!!
Forget her man do yourself a favour!!
