It’s hard for emotionally generous people to burn bridges. And yet, that’s what you gotta do to get rid of the embarrassing rash on your life known as the narcissist. It burns like iodine on a knife wound, and I assure you it makes no more sense to keep a toad in your life than it does to deliberately infect and pick at that knife wound in order to keep it sore and in your life as long as possible.
Bridges keeping alive a relationship with a toad benefit the toad, and only the toad. They’re really unhealthy for you. So, whether you blow it up in a blaze of fireworks, quietly burn it in a private bonfire, or reduce it to a pile of rubble in a final earthquake of ceremony and pomp: Get rid of the bridge allowing the toad access to your heart. That bridge leads to Misery, and Gaslighting, and Lies and Manipulation and Torment — all places where he lives, and where sane folk don’t wanna go. Look at it, closely: it’s not even that great of a bridge.
