Is she nervous?

I often see her speaking normally, laughing, and interacting confidently with her friends, including other guys she talks to. I had thought she hated me because we hadn't greeted each other or talked in a long time. However, the other day when we met and made eye contact, she tried to greet me but her "hi" came out very quietly. Then I noticed her fidgeting and then looking away, which confused me. Additionally, when I sat behind her the other day, she became surprisingly quiet, even though she is usually loud and talkative around her friends. What do you think?

We also used to greet each other and make eye contact before, But we stopped after I noticed her ignoring me up close, I saw her looking at me from afar tho
