Ghosting has now become my default experience on dating sites. I can't explain it either. I can't imagine a worse hell than this one. It's deepened severe trauma and brought me closer to suicide, that's pretty much it. Telling myself that people are shit there is not enough.
Now since it's obviously not normal at all, it can't be explained by my appearance or my behaviour or simply people's shallowness for instance, I'm trying to figure out how to fix this. Currently I've made an appointment with a new trauma specialist, I'm following another one on YT who offers free ressources about grounding oneself and fixing one's nervous system and I might see an energy worker next once I've figured out the grounding thing... If I don't collapse first obviously.
Your case might be more normal though but while attachment is normal, messing with people is not so I don't know of a better solution than figuring out how to fix what might repel people without your knowledge and how to develop solid bonds so you can safely deal with things.
Occasionally there are situations that can explain this normally though if the person is unwell, busy or whatever.
