When do girls call a guy cutie pie?

We met 3 weeks ago with this girl, she is 10-year younger than me but in her 30s. When we're messaging she calls me cutie pie, I know that it is something that she likes me but I don't like it. When do girls call a guy cutie pie? How should I tell her that I don't like such compliments?
