Whats up with this girl?

Ive seen this girl maybe like 4 times within a month of knowing her. We went dutch the first time, i paid for everything the 2nd time, we just chilled at her house the 3rd time, and she paid for our lunch the 4th time. However, ive never actually talked to this girl for more than 5 min. on the phone.....like EVER. All she ever wants to do is text. She claims that shes always busy but shes only like 22 and im 24 and have already grad. from college.....how busy can u be? School keeps u occupied but not that occupied and i know this cause ive been there and done that. Ive never met a girl that i couldnt talk 2 on the phone and keep them engaged but ive never even had that oppurtunity with her. Im pretty sure she sees other guys but why is she trying to keep her distance but still contact me occasionally? If ur not feeling me then why stay in contact periodically via text once a week? Whats the point? What is she thinking? Im not trying 2 toot my own horn but im a good azz catch. Thoughts?
