<human>: I have known this girl since last semester from a class I was in. Now we are in the second semester and I still have not asked her out. I wonder if I even have a chance considering my circumstances. Neither of us have each other's phone number or talk to each other anymore outside of one instance: I visit her at work on a periodic schedule. I am starting to feel like my presence is unwelcomed and therefore I stopped visiting her last week. I have asked her about this and she has no response. She literally says nothing. Her body language, depending on the week, is anywhere from receptive to cold. I used to walk in not knowing what to expect. This is the only time we talk in the entire week; otherwise, neither of us ever sees the other person.

Anyways, I am wondering if I went too far in not talking to her. I have no idea what she thinks about me and I do not want to infringe upon her boundaries, therefore I stopped. Her ambivalence is disconcerting and she has previously never communicated what she wants from me. I have asked her a few times and she looks at me like I am supposed to know. 

Last semester, we also never talked about anything deep, emotionally or intellectually. We had basic conversations and she seemed to be interested in me. I believe I misinterpreted those signals or was too late in asking her out. The reason I did not ask her out was because of the classic fear: rejection. Now, I am wondering if I can salvage this relationship by taking the next step or if I am delusional in thinking I still have a chance. My heart says to drop it, but I fear regretting that decision in the wake of potentially having this relationship.

Can you condense the text into three sentences or less?
<bot>: Visit girl during work, do not know if presence is appreciated or creepy. Have continuing interest in her and do not know if I should ask her out or drop it.
