I despise people that ghost others and I see it as nothing but maladaptive and sad. A person who ghosts is someone who lacks enough empathy to understand how damaging it is to others, it's someone who lacks conflict resolution skills, who internalized Internet block / unfriend buttons in their mind as a viable way to terminate any relationship.
When I was younger, people didn't do this shit. I grew up without the Internet and didn't have it until I was an adult, younger people don't realize it, but people didn't use to do this, and it's hurtful and infuriating how technology has affected this aspect of human behavior.
