Does she like me? Or am I just stupid?

So there's this girl that I've pretty well liked all thru HS. This last year of which her and I sort of connected, I suppose, and she acts/acted like she liked me and all, but I just never mustered up the courage to ask her out until just recently (the senior year now over). The reason I asked her out was because out of no where she txted me. So, I acted on it and eventually we went out. I thought the date went fine and what not. I took her home, we talked in the car for a while and walked her to the door (but only got a hug..). So I waited a few days and txtd her and she just didn't seem interested. I'm not rly over her, but I can't necessarily tell whether she cares to go out again or not. What do I do?
