Girl ghosts me after rejecting me but views my stories?

I was talking and texting to this girl for a few months then suddenly she just vanishes. She then stops texting me and responding. I try to talk to her in the workplace but she seems cold and walks off. I'm not sure but this behaviour is as if she found someone else. She also never likes my posts but always likes others of my colleagues. Why would this girl keep viewing my story if she rejected me?
