is she shy or just not interested?

[Jake]

I sit next to a girl in biology and since we usually have to work in groups I usually talk to her. She always smiles when talking to me but avoids making eye contact, even if she is looking at me she will quickly turn away, if I look back at her. She is also always fidgeting with her hair, fixing it and messing around with her phone the entire class she isn't texting on it either just going on random sites . I always have to initiate the conversation or she won't talk the entire class. Although for a few classes now she does make short eye contact and I have tried talking to her after class but she acted really strange and afterwards walked away really quickly. I really like talking to her since we have a lot in common but things usually get awkward between us because she doesn't talk much unless I ask her things about herself. She always asks me for help even though she is smarter than me and she always sits next to me even if the other seats are empty, but I haven't seen any signs of her liking me except her fixing her hair and fidgeting with her phone
