I'm so sorry about your experience. Narcisissts will ruin your life. I am hoping and praying for you to safely find a way out, because it is literally the only way to be free from his negativity and abuse.

He is dulling the shine of such a brilliant talent, and he doesn't appreciate or deserve anything you have to give. I recently wrote a poem about my experience with a narcissist and I'd like to leave it with you. Please know you have my full support and I'm sending love and light to you and your mother.
