I've just written a letter to my ex. I haven't sent it or anything.
Jesus... I laid into her. I was writing it for hours. Just flowing out of me like it always does. It started out quite coherent but towards to end I'm just hurling abuse. It's basically all my pain on the page.
Now, place the letter off to the side for a few days. Come back to it and if you still want to send it then do so. BUT as Apollotech said, no expectations. This is FOR YOU letter. If you have a T take it there and read it out loud. If no T then find a good friend who you can sit with alone that you are comfortable expressing yourself with and read it there.
Under all this anger are a lot of hurt feelings for someone you still probably love. You may consider saying that too, if it is true.
Keep us posted. I am not where you are at because it is still too fresh but I have a similar letter to write to me ex.
