Another thing I should mention, her behavior is somewhat inconsistent so it's hard for me to even say with certainty how she feels about me. For example, last week she and a couple of the others were going out to lunch on break and she called me to invite me to come with them. And a couple times she asked me to come walk with her to the break room to get coffee in the mornings. There was also one time recently where she came over to my desk to just chat for a few minutes. She also responds to my texts in our group chat. All this would suggest she wants to be friends, but at the same time she has shown unmistakable signs of being annoyed with me. It is hard to say what is going on exactly.
