"Pending"snapchat problem

A girl left me in pending for like 3 or 4 days showing me that that person left me in pending for that time, so I was kinda going over it, but today I opened snapchat and it shows that I've been in pending for only like 23 hours. I just wanted to know if this could be a glitch or she actually added me back to Snapchat and unadded me for trying to call my attention or something like that. What do you guys think??
