Is she using me as an ego boost?

So i met this girl but i didn't show interest at first. She lives far away from me. After coming back to home i started to have feelings. So i started texting her. the conversation were just friendly talk no flirting. She would usually reply a few days late and i know for sure she's on facebook.. I eventually texted her that she was cute but didn't get a response. I'm done with her though. It sucks waiting days just for a message -_-
