I think it's useful to remember that not all ghosting is done by totally callous arseholes.
Sometimes, you've been talking maybe even had that first date... but you're not really feeling it. Not sure how to phrase that (see people on here asking how, quite a few times). Or you're dating / speaking to others too, and you're not sure if you like someone better.
You don't plan to ghost. But because you're not sure what you want, and if you are sure you're worried how to say it... and, you barely know the person so you don't feel massively obligated.
So you don't intend to ghost, but it's now the second day, and you'd normally text every day... you'll find the words tonight. Then... well, he did text last but he hasn't texted again, so - maybe he isn't bothered? (you hope, cos it's easier then)
Next thing you know it's day 3 and you think - well, no more from them, they know you're not interested. So then, isn't it a bit shitty to twist the knife and say "hello again! I'm just popping up to say I don't like you!" Ugh.
So you leave it. Next thing you know, it's a week and you've ghosted them.
Now I haven't ever done that, but I have stalled contacting to close things through awkwardness and I really see how that can happen.
It's not polite, but the driver isn't meanness either.
