What about, she wanted to bring you into a relationship/courtship frame, which would initialise with you dating her and treating her nice to get her to Fuck you.
She knew if she fucked you straight off the bat it would be like the one night stand you had with her and bye bye the next day....
Lol this is a typical example of not treating a girl like a human.
I'm guessing you had sex, there wasn't a lot of conversation the morning after, and you didn't contact her apart from the text you mentioned?
You've basically treated her like cum-bucket.
I'm sure you won't make the same mistake next time - go out with her or something, have a drink, play pool - girls do have uses other than sex - seriously!
