Is it typical for girlfriends to get jealous of each other?

I went out with a friend I had not seen in like several months because she works in another city. She posted a story with me and then this girl from our program texted her saying “what about me?”. I just don’t get it. Apparently she was disappointed she made time for me first but that’s normal because we were closer friends anyway. I asked her if it is because she doesn’t like me but apparently that was not the case. Apparently she is insecure? Has anyone else experienced this before?
