Am i over this girl or am i still not?

Theres was this one girl in my school i really liked we even had sex but she dint feel that way about me to put it in simple terms she lied to me told she dint want a relationship but then got one like a week later. Well i was depressed or like a month. Now that feeling is gone and i feel like i dont care. But sometimes i have dreams about being with her and about us going out and stuff. So am i over her or am i still subconsciously in love?
