Why does this girl act so nervous around me?

Anonymous
I really don't know what to do with her. Some days she will come up to me and say hi and start chatting. We know each other so its not like I'm a stranger, so she will start the conversation then I'll slowly take over and ask her appropriate questions about her day or what has she been up to. Her initial confidence then quickly turns into being all nervous and fidgety, she laughs and smiles, but that could also mean she is not enjoying it and is uncomfortable, so I try to look for an out and end the conversation.

A little bit later we may run into each other again and she'll start asking me questions and showing a "I want to talk to you" vibe but when I start, she'll start the not looking at me or looking away while still smiling, which again I can't tell if its one of those "leave me alone" smiles.

She is pretty consistent when she talks to others, she starts friendly and finishes friendly. Maybe I look into it too much, but I really try to keep the conversation light, nothing too personal or obvious flirting, I try to be funny and she still acts like this. She is usually on her phone constantly looking at things, I'll talk to her and she is obviously listening, but she either just looks at me and smiles or answers without looking away from the phone.

I'm very nice to her, I'm polite, respectful and I have shown her a sweet side to her that I rarely show. She is a little shy but she is chatty with friends but she has known me for over a year and she still acts like she doesn't know me, even though she remembers and brings up stuff I've told her months ago, what is with this lady? Do I make her uncomfortable?
