So frustrated i need Help?

i asked this girl to hang out a few days ago and she said "yes if i dont have anything going on then" well that was on friday its now saturday night and i asked her if she would like to go to the mall on tuesday (the original planned date of when we were supposed to meet up) she said "idk if i can" so i asked what she had going on "a family event" she responded. So i said another time maybe and then she said "g2g byee" i was like wow ***** way to lead me on.... i was really excited cause i came wayy out of my comfort zone to ask her. She told my friend i was "a nice guy" which that doesnt mean dick... so what should i do? ask again? or move on?
