I think the term you mean in ghosted, from the word ghost. Ghosting is used to describe when someone you are dating does not break-up with you (they don't even send you a text) - instead they just disappear from your life without any explanation. In a sentence. "' I thought things were going so well between us and then he just ghosted me"

I've never seen that word before, also google comes up with nicknames for people but no definition..
