I guess she's never heard of the concept of "He's not into you". He breaks their "date" and says he has to tutor someone. You mean he had an emergency tutoring session. Uh, okay. Then she justifies his not contacting her, he's working, he's busy, he didn't see her message, he is scared, shy, blah blah blah.
Sorry, but if a guy is interested, a girl will know. He will call and text when he says he will. He would have made a definite date with a plan even if he couldn't have that date until a week from now. He would have said "We will go out on Friday. I'll be there at 6 pm"
She is embarrassingly without pride by saying "Oh, I'll text him one more time and that will be it" when he's already had enough chances. But he DOESN'T WANT TO. Even if the guy just wants to get his dick wet, he would have made a plan. She has no dignity whatsoever.
(Yes, there are a lot of guys who are shy but he is obviously not one of them if he meets a girl in a parking lot and can immediately root around looking for something under that fupa)
