Am I delusional?

There’s this girl in my anatomy class and I really like her and for some reason I feel like maybe she might be into me too?? We work together on everything and she’s always touching my shoulder. And she’ll always go get me the assignments at the front, or go get the models and tells me to sit back down. And she uses a really cute voice only when talking to me. But we only ever talk about the class, occasionally we’ll talk about our majors and stuff tho. Not to judge a book by its cover, but she “looks” straight, and I don’t wanna get my hopes up or anything. I wanna invite her to study with me after class, should I do that? And how do I flirt with her, or like figure out if shes into women? ┗( T﹏T )┛
