Why would a girl treat me special and then say I'm being self-important and that I'm not special?

I've been talking to this girl for a few days and we've gotten to the point where we've become very intimate and open with one another. The other day she said something I didn't like and I tried to tell her that she shouldn't say or make crude jokes. She called me self-important in doing this when I was just trying to help and told me "I was more special than anyone else she's been talking to". What did she try to mean by this if she did trying making me feel special before?
