So I went to the mall yesterday to buy some clothes and I saw the cutest girl walking around. So I went up to her I introduced myself and asked if she had a bf she said no and I asked if she wanted to hang out right now she said yes. For about a half an hour we just talked and we really connected I kept her talking the whole time asking her questions about herself. Then at the end when she had to go I asked for her number and she gladly gave me her phone so I could see her number and I put her number in my phone. So I texted her about an hour and a half later simply asking her if she wanted to do dinner or a movie sometime and its been 24+ hours no response what the hell did I do wrong. I'm going crazy trying to retrace my steps.
