she wants you to go to her house and you question her motives? get out of the philosopy and go for the girl you dunce
Look, I can tell she is physically attracted to me but I want more than that. Frankly, I don't like it at all. I'd prefer if I had to work for her admiration. I would hate to have a relationship with her just based on that... That's all I am really afraid of.
Why not offer to pay for her time if that would make you feel more comfortable?
Ask her what she would deem to be a fair hourly rate, and offer to pay her in bitcoins?
