Dealing with a narcissist can be problematic. When you see that the narcissist is enraged, do not continue engaging with them. Physically distance yourself from them as much as possible, ignore them, or avoid any interaction with them.
The narcissist enjoys seeing you rattled and upset.
For your well-being, make every effort to stay calm.
The narcissist finds joy in watching you react to their rage.
No response is the best course of action.
Once you see that the narcissist has become enraged, you should immediately remove yourself physically from their presence. With narcissistic rage, you can never be too careful.
When arguing with a narcissist, be sure to avoid raising your voice.
Everything is always about the narcissist, their wants, and their needs. When you understand this, it is easier to deal with them and the narcissistic tactics that come along with them. Understand that this is a personality disorder that has nothing to do with you and was probably established well before they met you.
