Ok so i randomly found an alone pretty girl at a mall. I tracked her a little bit and i found out she is kinda in rush. So i walked up to her and said she is pretty and i want to meet her. We started a small talk and because i didnt want to be annoying and let her go, i asked for her number after a bit talking and she smiled at me and gave it to me and got blush. The same night i texted her " this this is a VIP#, store with care" and at the end i mentioned my name. She texted me back. "Haha,ok:)" . But the next night when i texted her" whatcha doing girl? :)" she didnt reply.What does it mean?. Should i text her again or should i just move on? Is she interested in me or not?
