Hey guys, this girl deleted me off facebook and still flirts with me in real life, what do i do?

This girl (attractive) and I first started to talk at a football game,however the next day on high school she ignores me while i tried to say hi.And through a three months period she avoids me but in a party she began to talk to me and started to flirt too. Since then she talks to me like nothing happen. The funny part is that she deleted me on Facebook, and I don't know what to do.

just ask her
