Does this girl dig me?

Just asked her out for a semi date. She agreed to join me for a free golf lesson and she doesn't play golf. She is also very friendly to me and we talk a fair amount on Facebook. Plus, she asked me to study with her and we don't have a real cl together, which would need studying. I just am not picking up too many ques when we are in contact (@ work). For instance, she rarely glances at me, and talks to me just a little bit. She is not the quiet type though. Another strange thing, she has failed to return my calls/text messages more than once. For instance, we were supposed to go out to the bars and she didn't answer her phone; said she fell asleep. Also, she said she'd let me know when she finished working on something and she never did. I am really confused, but I think it is awesome that she wants to go out to the driving range with me. My intuition would say she likes me, but I just cannot seem to figure this one out with certainty.
