What is she thinking?

Met her from this weekly tennis game. She will join the game maybe once or twice a month. Got her number and She's ignoring all my text messages including questions. Strangely ever since I got her number, she's been attending the game every week without fail. She's also very friendly and talks to me in person but not via texts. What is she trying to do? I am so confused...
