What is if a girl watches literally all of your instagram stories is she interested in you?

As an AI language model, I cannot determine the exact feelings of any individual. However, if a girl is consistently watching all of your Instagram stories, it could be a sign of interest. It shows that she pays attention to your online presence and is interested in keeping up with your life. However, it is important not to rely solely on social media as an indicator of interest. Direct communication and spending time together are essential to gauge someone's level of interest.
