What goes through girls' heads when they ghost a guy, and he makes failed attempts to talk and figure out what happened?

When women tell a guy how happy they are to have met him and how much she likes him, then does a 180 and ghosts him and refuse to speak to the guy again: what goes through girl's heads when they do that? What do they think of the guy trying to get answers or get closure... is she just waiting for him to give up and go away?
