Thank you for your post! I can relate to it. I have been in many abusive relationships. Writing a letter is very therapeutic and I have written a letter similar to yours to my sister. The things she did to me were similar to what my sister did to me, line by line. She also did many things to me that I hope your Ex didn’t do it to you, I haven’t mailed the letter to her as that would make her feel good about herself for being able to control me that much. I suspect your narcissistic X would feel the same. Wish you the best with healing.
