Did he ghost because he's intimidated?

So there's this guy I've been seeing on and off in the past. We were both toxic and I could tell his mental health wasn't the best. I do think he liked me for numerous reasons, I did think about these reasons logically and talk to friends about it. A couple months ago we stopped talking. Recently he reached out and then ghosted, we were talking about our lives and his isn't going too well while mine is. Is he intimidated by my achievements and they make him feel kind of bad about himself?
