Need a hint

I recently met a girl at a corporate party. We exchanged phone numbers and in a few days, I decided to invite her on a date. The girl came from the provincial backwoods. One. Rent a house. She is 25 years old, seemingly adhered to 6-7 out of 10.
Unsophisticated, introvert. She dresses as if she were going to church. I talked a lot about the spirituality of relations, etc. etc. It is impossible to express foul language with it and also express slang, or it will be hysterical. All her free time she either walks around the city alone, or sits at home, too, alone.
Several times went with her on a date. Tried to hold, to take her hand, but she stopped it. But she periodically took me by the hand or hugged a little. One word - frendzona.
After the fifth meeting, hell began. She began to talk about her life. That her who does not love, her ideas about the world no one understands, etc. .. That men should be knights, and girls behave freely. That she will be a rich photo model, and that she will have everything - a sports car, an expensive beautiful house, fans. And then she was hysterical and she ran away from me when I tried to protest her nonsense.
In the Steemit, she removed me from the subscribers.
I write to her in a month:
-Well, how are things with the model? Do you know how to make a model?
In response, again swearing - that I'm nobody, but she's everything. And that money does not smell.
A week later I wrote again:
Let's meet, I want to have sex with you.
And she said YES!
Just finished - "The meeting chtogit 7 thousand hryvnia!"
And she came to me! I flinched at the doorbell, although before that I lured them to me, in some sort of hotel room, but I refused.
I met, discovered and something went wrong, I decided to tell her from the doorstep, that she does not have the money for me now, and the fact that she came is a surprise. She left, she did not even finish her coffee.

I have a question. Is this normal female behavior? She does not look like a prostitute, but can she work on it temporarily? And for an intelligent moral girl, is that good? Or is this a deviation, a consequence of the moral trauma of the past, do not engage in sex for free?
