Truth is, you cannot be anything other than impervious and indestructible (as a being), unless you agree otherwise. So stop being so damned agreeable that you can be hurt!
I know it’s unpalatable for me to spoil a game, if the game you’re playing is “I’m a victim! He hurt me!”. Just recognise that it is a game. After all, as the great bard said, “All the world’s a stage. And all the men and women merely players.”
