Not sure what to do? 10 pts!!!?

i met a girl a few days bak on the bus. when we got off the bus we exchanged numbers. we went out on saturday together but were with our friends. during the nyt it was pretty much just me and her talking to each other and after the nyt she texted me saying she had a gr8 time and we shud do it again soon. then a few days l8r i txted her askin how her first day at uni had been. when the texting convo ended she asked me if we were still on for wednesday. however after i told her what time i was free she sed she wud get bak to me and never did. it's confusing coz she seems quite forward and then just seems to bak off. i'm not sure wht to do. shud i txt again or leave it?
