Girl talks to other guys normally but nervous or uncomfortable with me?

I saw her today talking to a guy, possibly about studying or whatever, and I didn't realize how much of a talker she is. It made me remember the times I used to go and ask her questions, but she always replied with limited answers. Also, she avoids eye contact with me – every time our eyes meet, she quickly looks away. I'm wondering if she's just nervous or if she really dislikes me. The reason I'm asking is because the guys she talks with like this aren't really the best-looking, and I can't imagine they are her type (respectfully)
