He called you a "toxic psychopath" for telling him that his best friend was making you insecure with her unnecessary closeness. He was always close to his best friend, Sarah; she would hug him and even sit on his lap in front of everyone, and he never said a word. In fact, he praised her and hugged her, pulling her closer, leaving you as a mere spectator.

One day at a gathering of friends, he spent the entire evening next to Sarah, caressing her waist. When you asked him to stop, he mocked your "insecurity" in front of everyone, hugged his best friend, and kissed her while his eyes never left yours. He said,

"So you can work on your insecurity." Everyone laughed. Sarah smiled smugly and said, "How pathetic you are, always begging for attention."

And he looked at you with such an arrogant smile, waiting for your reaction.
