Told me I'm out of his league, then ghosted me?

He is either super confident or he hates himself. Even though he seemed very ballsy in the beginning, later on he started telling me how I'm one of those "pretty girls" and he is a "dork". After I tried to explain how wrong that is, he ghosted me. I don't get this at all.
