Girl Blocked me but still talks to me and teases me when we see each other?

She has strong feelings for me but says she’s busy with classes and has me blocked on everything out of nowhere and never told me why. But continues the communication in person when we meet. I’m not sure what to do about the situation, but I just want to improve communication between us.
