Girl Problems, Anyone want to help?

Okay so there's this girl Alexia in my school. She's in two of my cles, and we see each other a lot during the day. She talks to me a lot in school, and we text and talk on aim a lot also. She recently dumped her boyfriend and told me everything the night it happened. Usually I'm the one who engages in the conversation and it seems that she is just a little interested in me, but not really. How can i get her to fall for me, and want to be around me a lot more?
