It could be that you are busy, had some issues, many other reasons. The whole point of a clear signal is that it's easy to understand and with as little room for misunderstanding, which ghosting is obviously not. If you want to ghost someone, by all means, but it's def not a clear or direct signal.
Not to mention, I thought the whole point was that you don't have to be direct and clear about it and hence won't have to face the possible backlash.
Your need for “closure” or whatever doesn’t matter.
I'm not sure what you mean by this. I didn't think my "needs" were a subject of the discussion lol
