She told me she liked me, but now it doesn't seem that way.. what should i do?

This girl shelby and i have been spending alot of time together, going sledding, watching movies at her house, whatever. one night she told me that she really liked me, and i told her i felt the same. Now sometimes she wont answer my texts, but sometimes she will text me first. some days she will tell me we should hang out and spend some time together, but half the time those nights end up with her being bussy. last night we were supposed to hang out but i couldnt because my uncle came in town from germany so i couldnt make it over to her house. today she asked me to hang out and now i find out she is at a club instead. idk what to make of all of this. shes not one to mess with people or play with them, but i just dont know whats gonig on. she seems intrested in hanging out with me alot, but nights like tonight where she went to a club instead just really makes me wonder. any thoughts?
