What does the dumper feel or think if they get ghosted after being in contact?

After dumping someone, then getting back in contact with them and having some conversations with their ex over a period of time through text, then suddenly one day they get no response at all, like the person disappeared, nobody has seen or heard from them what does a dumper start to think/feel? Is it the same as a person that was dumped feels if they get ghosted, like the worry and sadness, and feeling they did something wrong? I’ve always wondered this
