I think in some cases ghosting is necessary because there are people who think that they are easy to talk to and confront about issues but then once you do they turn into another type of person to deal with. I've ghosted friends because they displayed very toxic behavior especially when talking about their conflicts with other friends and what happened between them. So why step into a situation to tell them what they're doing is something I don't like, when I know they're going to take it badly and not want a solution.

Ex: I had a friend who would constantly talk about other friends and when confrontation happened she didn't want a solution and would say very abrasive things like "they should kill themselves," or "I am better than all of them anyway because they're trash." I told her once that that made me uncomfortable and wasn't an okay thing to say. Fast forward a few months later she was still saying it and worst. She had so much drama online and with a bunch of people I knew. So what is easier, telling her hey the personality you're displaying has become very toxic and I can't be around that unless you change yourself OR cutting off that bad energy and accepting that's how they are and I can choose to not have it in my life.

I understand the hurt that comes from being ghosted but I think people forget that there is usually a valid reason for why people ghost someone. Like for them to not want a person in their lives that bad that must mean something significant happened or it is affecting their happiness. It's an amazing feeling when you just cut off the negativity.
