I do feel this. I've had long term friends just ghost me after a disagreement. It's painful to the point of traumatic.

That said, people I'm about to break up with a friend, family member, or partner, they have a fuck ton of warning it's gonna happen. It's a bit like a job, where people deserve escalated warnings before just getting their keycard locked out. I try to be very explicit too, like "X thing makes me not enjoy hanging out with you and I don't want to be your friend". And said friends and family always have some avenue for apologies, maybe we're not friends on Facebook but they know my email.

For instance, I've given my parents 7 years to apologise. They still have my email, which they only use for birthday wishes. (I've told them to stop). They're just far too self centred to care about feelings outside their own. I'm a happier, more grounded person for having zero hope with them.

This, i almost ghosted my best friend 7 years ago because of the refugee crisis in europe birthed a ton of arguments between us and i really started to hate his guts but thankfully he did his due research and now at least acknowledges that most of the world's troubles come from capitalism and the US empire. I don't feel like i need to cut off the people who i still dont agree, i just keep them at a safe distance.
