Am i doing something wrong?

There's a girl I have a crush on and have had a crush on for quite some time, but I never spoke to her because she was always quiet. I recently, within the last few months, began speaking to her and found out she is a really out going girl and is alot of fun and such a sweet heart..i told her of my crush and she seemed okay with everything and we still talk almost every day..sometimes for hours and its lively and other times its a bit boring...i asked her if she'd like to hang out and she said she'd get back to me this week..i think she likes me, or is interested in getting to know me better...but im really not sure, she is really difficult to read. and i dont want to push harder in case it turns her away but i dont want to back off in case she is waiting for me to make a move...please help, 10 points to best answer
