Unfortunate Fate

Everything has just changed,
the person who used to be my really good friend is now no more than a traitor near me.
This person wants to take everything from me.
It's really sad to see people being used.Actually being used by their own kinds.Yes,there are some kind of human beings who love to play with other emotions.Well I call such people"tyrant".
The tyrant actually doesn't leaves you with a broken heart but also stamps a non erasable scar on your personality which can't be removed and later becomes part of your future and past.
How would you feel for a person who is a victim of that tyrant and he never realizes the fact of him being used.That person is actually cheating on himself by denying the fact and still accepting the tyrant. Wait now there is a turn in the story there is a person who is actually willing to help the protagonist and help him get out this dark sides. The protagonist gets really pleased and welcomes the existence of this new character in his life. However he is unaware of the fact that he will be ruining his life again by trusting more people but he is helpless because he wants people to whom he may open his thoughts too. Unfortunately the person who he actually chooses to trust ask him  if he could aware him with his past.The protagonist agrees but he  is afraid as he knows that again he will be betrayed.He denies to hear his doubts and hesitation and tells him everything. The act was proved to be a wrong decision as he left him.
The protagonist cried helplessly on his unfortunate fate but it was too late.
The protagonist has a friend he is more like his sibling ( not in real life sibling though).
The friend tries to explain the fact to the protagonist but he denies to  hear any of that.
Most of the times "They both encounter an argument between them because of the tyrant.Why doesn't the protagonist forget about tyrant?
Ans: He actually can't forget the good memories spent with the tyrant.
WHEREAS THE TYRANT DOESN'T EVEN CARE IF THE PROTAGONIST EXIST OR NOT.The most sad thing is that the protagonist is slowly going to lose people all his friends after the person who doesn't care if he exists. THE REALITY IS THAT THE TYRANT IS NOT A TYRANT BUT AN ORDINARY HUMAN BEING WHO TREATS EVERYONE EQUALLY AND THAT's GOOD BUT IN THIS CASE THE PROTAGONIST IS TOO IMMATURE TO ACCEPT THE FACT AND HE THINK THAT HE WAS BETRAYED AND THAT"S Not TRUE AND THINKING ABOUT SUCH STUFF REPRESENTS THE FACT OF THE PROTAGONIST BEING REALLY IMMATURE AND DUMB HEAD.
