First of all, she said that you are a straight man, that is, a outspoken boy. These boys have no intention, but they are kind to girls from the heart, so they are often affirmed by girls. Now the girl says that you are straight, which means that she still has a good impression on you and still likes you!
Secondly, she said that you don't know her at all, which is obviously blaming you: you don't know her emotions and hobbies, so you lack flirting skills. This has clearly expressed her hatred for you. It's not that she doesn't like you, but that she wants you to be better and make them get along more romantically and lovingly.
So, you can be saved completely. At the same time, you should carefully analyze the girl's hobbies, learn some love art as much as possible, meet the girl's requirements and please her! So that the world of two people is more romantic and sweet!
