Why did I block all of his account? To prevent him for doing communication. To stop all his crap that perhaps makes me agree with him again.
If the communication is a rare thing in this realtionship, why don't we just stop it?

It's been many times he rejected to accompany me when I ask him. Several times he refuse to help me.

He's been so full of himself. He even doesn't need me in his life. His life purpose is for working and others crap. There's no space for me in his time.

 I found more unhappiness and disappointment rather than happiness. Why should I continue seeing him.

 Some people and even I admit he has potential. But his potential doesn't have a thing with me. The potential have no business for making me happy

Let him be
He is happy in his own. He doesn't need me around. And I can continue the life by myself. I'm sure one-day I will meet the better guy who deserve and appreciate my presence.
