If this is indeed a real question OP, my opinion is run far away and run now. None of these situations ever turn out good. It will never be the relationship you want. She could never go back to a normal job again after the easy money she has experienced. You will only be the desperate guy that was so lonely he had to resort to pretending he was in a relationship with a p4p girl.
She is ok with it because she keeps her money while you accept that ridiculous relationship status. It makes her look good while you look like a fool. You would never want anyone to know the truth and you know it lol. You don’t move in and play house with that, you rent it, plain and simple. Quite simply, if it flies, floats, or fucks rent it lol. Good luck.
