Why does this girl talk to me if she's not interested?

She has shot me down twice, but she still comes over to talk to me about things in her life. When we met, I invited her to stay longer to keep chatting but she said she had to go (friends were leaving). The second time, I went to her lab (other workers were around) to go out to eat but she said she'd go if others were going. I randomly bump into her at the store, both talks she talks to me a decent amount of time (at least 15 minutes) about how work is going, how she isn't sure if its going to work out. I saw her tonight but I tried ti avoid her. She came over and said Hi to me and started talking about job stuff. How she had interviews, not sure if its something she wants to do. How she's disappointment with her stuff. Asked how I like my stuff. Told me what she's cooking, etc.

So what's the deal?

She stands over beside me and always looks me right in the eye.
