My Ex-Boyfriend Attacked My Best Friend

Qi Huachen is the ex-boyfriend of my best friend Li Ziwen. NPD. Narcissistic personality disorder. He fucked my bestie to the point where I wanted to commit suicide several times. I spent a month getting close to him and trying to please him. He thought he had me. He sent hundreds of messages, blocked me downstairs, squatted at my knees, and said, "I can't leave." He thought I understood him. He thought he had met the only person who did not urge him to reflect. He whispered in my ear "I love you" and said "you are the first and only one". I laughed. I said, "Qi Huachen, Li Ziwen is my friend." Intention: love yourself
