You should try to re-read what you have posted while asking yourself if it sounds like someone who has moved on. Sometimes we try to convince ourselves that we are 'over' things, but continue to let them occupy our thoughts, which is quite contrary to being over them.
If you've both really moved on from each other then it wouldn't really matter who was successful with who, or when they deleted X account, they've gone their separate way and it's best to do that, yourself. I'm not trying to make you feel bad, though, it is very human to have a hard time letting go of something that we liked (even if it went bad in the end).
