Does this mean she didn’t like my personality?

There was a girl who were crushing on me for a long time. She is really pretty and I asked her out. Before we went out we kissed few times. Two weeks after last kiss we finally went out. After first date she turned me down. I dont know what i did wrong but i had to be really bad when she turned me down after first date when she liked me for a long time
