Sometimes a blatant clear rejection won't do because some people would rather hang on to a fake promise. A fake promise doesn't even have to come from the person who is doing the rejecting, the fake promise can be self imposed.
Why would someone self impose a fake promise on themselves? Well, it's usually because of Fear and or out of vengeance. They may say, "No, it's not that at all", but their actions speak otherwise.
On the positive side, when someone has told you to "Get Away- Leave me alone", it just may be the blessing needed for all those involved in a not so positive interaction. Yes- it usually allows all parties to explore new avenues of life without the complications of ongoing negative interactions. It may be the breathing room that one needs to discover their true inner potential!
