I get it. I'm definitely not an asshole; even my ex will tell you that. People seem to like me. I’ve never gotten any feedback from any manager or team member of mine saying anything about bein difficult or anything. I try to help people out when I can.

The times when I have contacted people, it's been about as well received as I'd expect a contact from a former coworker to be. It's just that nobody ever initiates. I'm not getting anything out of trying to maintain these relationships except stress, so, why bother?

And, now, someone (actually 3 someones, because I was at +3, now at 0) has gone and downvoted my original comment for whatever reason. ¯\_(ツ)_/¯

I'm in my second role in Australia. Can't say whether it's a thing but people from my previous role (people still there and people who have moved on) definitely keep in touch with each other.
