Girl's Behavior

Why would she pretend to not see me?

I knew this girl at work and I felt like she was flirting with me before. She’d help me do stuff and when I had to stand on a chair she helped hold it for me and told me how strong she was and she also called me cute before. I also felt before she would look for any excuse to talk to me. They took the mask policy off at work and we no longer wear masks and today was the first day we saw each other without masks and I caught her glancing at me when she walked in and we made eye contact then I looked away. Then when she came back out I caught her glancing at me again and I mouthed the words hi and she just left to a different sort of the store to talk to the manager. She kept coming near me today but wouldn’t say anything at all. I know I’m pretty without my mask lol like two people called me gorgeous today and I do get that frequently. We’re both girls lol and I don’t think she’s completely straight. What’s her deal?
