When you hear someone talk about a friend suddenly ghosting them, trust and believe they are in denial about the reason majority of the time
As the friend who had to dip after constantly stating my boundaries and overcommunicating when multiple friends hurt me, I have gotten feedback that people thought I left out of nowhere.
Most people have a hard time admitting when they are being inconsiderate or bad friends. Because they deny so much and do not self reflect, the rejection seems to come out of nowhere. For most people it isn't popular to admit that they took others for granted, disrespected their friends, and showed a lack of care.
Disclaimer: This is not for cases where they say absolutely nothing and ghost you. This post is about those who tell others it came out of nowhere.
