Even if he cheats, he won't find anything here.

If a player, after losing, intentionally prolonged the game to force you to quit, then that should have been addressed immediately. When you are accused of something, you need to defend yourself based on the facts, not by referring to your uniqueness (and especially not by saying that you will resolve everything and then fail to do so). I think you can check the save file to see how justified he was in expecting something else from the game.

My self-esteem is fine.

It's normal to get angry at a player who is behaving inappropriately (if that was the case). Saying, "I am unique, and the rules don't apply to me" is not normal.
