I dated a girl that said that to me on multiple occasions. She didn't tell me until after she knew I liked her, because it is a bit creepy at times.

Well, there are so many things to say, and it depends how romantic you are feeling at the time and what kind of character both you and your listener have - and exactly what kind of relationship you have had up to the present time.
