First things first, dispose of everything that reminds you of them. The things that they gave you as a token that they are still thinking of you, that things are still going strong. Box it up, throw it out, and if you’re really ready to let go, burn it. Take the photographs of when things were still going good, off of your wall and off of your computer. But most importantly, remove and erase the photographs of when you were happy. Forget about how good you look in their flannel shirt. Cut it up and bring a piece to all of the places that you ever went to together. Leave the memory behind along with shreds, and along with the pain. There is no looking back now.
