Is she into me?

Hey there,
Lately I am getting some vibes of my friend and I don't know what to do with them. She has never had a relationship before, so I can't tell if she is straight or gay. But over the past weeks she Always seeks my attention and gives me looks like she likes me. I really like her since a long time. But I don't know what to do now. Should I talk to her about it? Should I give her hints that I like her?
