In addition to the good advice already given , if you see pursuing this as part of your destiny and learning a valueable life lesson why dont you just say to her that you like her and want to be her freind and hang out for free but are willing to subsidise her for sex and see what she replies. You might be surprised at her response.
Even if she says shes not interested it might help you out of your mindfucked state , if she refuses its clear shes just a moneygrabber , if she accepts youl probably find out it isnt what you had hoped for and lose interest pretty soon, or you might end up finding your soulmate, who knows.
