Stared at silent treatment or little talking and talking to others more than me?

I asked out this girl at work and yes I know don’t shit where you eat. She led me on basically and I’m not gonna lie it hurt and I spoke to her more than I should have. Then I asked if she had a boyfriend and she said no but I knew she was lying. Since then I’ve not spoken to her at all. Now when I see her she stares at me with a dead look and giving me eye daggers which I ignore. I give her one worded answers and she likes to talk to people in front of me. From previous conversations I know she’s not happy with her current boyfriend or whatever she has. I can now say that I’ve moved on. Why is she so angry with me?
