How to write a hurtful and chilling sentence?

Hurting and chilling words are written like this:

1, pretend not to care about your ridicule and leave with a smile.

2, I ask too much, so be it, chilling, maybe I just treat you as a friend.

3, a fate, two hearts and three lives, four years of separation; Fifth watch, six songs move seven strings, and I have no sleep for eight nights; Nine chains, ten miles across, chilling for a hundred years; I miss everything, but I am helpless and my eyes are cold.

If I don't love you, I won't miss you, I won't be jealous of the opposite sex around you, I won't lose confidence and fighting spirit, and I won't suffer. If only I couldn't love you.

You should live well without me. This is the only thing you can do for me.
