Please google the word “promise”.
I don’t think the person who is repeatedly using the word “fake promise” understands the meaning of that word.
When someone is a stranger everyone are always polite.
When we get to know someone is a predator and a psychopath,
we are allowed to take a step back from that person.
No matter who it is.
When someone is saying they are not interested based on your behaviour, you are supposed to stay away.
You cannot bring up the past where we had few good exchange.
After we get to know someone’s true colors and true intentions we are allowed to disengage with that person and change our minds.
