Why would an ex girlfriend stare but not talk?

Anonymous
My ex girlfriend that I dated for 8 months still stares at me in our classes together, but acts cold when I try to talk to her or doesn't text back when I text her. I'd catch her looking at me and sometimes she'd look away really fast or she would maintain eye contact with me. What's up with that?

We broke up because she needed space
