I cut off contact with my narcissist father and stepmother about 8 or 9 years ago. I had previously cut off contact for a year or two at a time, but would feel guilty and reconnect and nothing changed. This time it's permanent.
Since then, my mental and emotional health has vastly improved. I have accomplished more in these years than in all the previous ones. I now have a great writing gig and life isn't perfect, but it's better now than ever before. If I ever did speak to them, the only thing I'd say is, "I couldn't have done it with you."
No you won't, you'll just yell at them anonymously online. We know your tricks!
