It’s hard to know if you deserve it or not, depends on what you did.

You aren't being ghosted, dude. To be ghosted you would have had to had done nothing wrong. You self admitted you fucked up. You just got dumped. And by the way this is written, you thinking this is ghosting, you saying your life is a story that is somehow interesting enough to call anyone a protagonist or antagonist, etc, I'm not surprised. Get over it.

Actually I think most people are their own worst enemy.

I can feel the “missing missing reasons” from all the way over here.

Are you by any chance a teenager?

I had this happen to me. Sometimes we make mistakes and lose people that are important to us. It's a hard learned lesson but I've never repeated those mistakes. You won't either.
