We broke up and she has been invisible. She has not posted or deleted my questions recently. What does she mean by this?

Maybe she still cares about you. She is invisible because she doesn’t want you to see her online. She can see you when she is online. You know that he didn’t post anything, which proves that you are still observing her movements. She also knows who is entering today. He has taken her space, so let’s go get your girlfriend back! Don't give up or you will regret it. Take action!
