Think of ex as a puzzle piece that used to fit perfectly in a puzzle. It used to be part of a picture, but now it’s no longer there. Maybe the puzzle changed, or the piece just didn’t fit anymore. An ex is something or someone that was part of your life but isn’t anymore, like an old friend or a toy you don’t play with now.
Another way to see ex is like a bookmark in a storybook. You read the chapter and loved it, but now you’re moving on to the next chapter. The bookmark reminds you of the part you finished, but it doesn’t mean you have to stay there forever. An ex is like that chapter you finished reading.
Imagine ex as a favorite shirt you wore all the time. It was comfy and made you happy, but now you’ve outgrown it or it’s not your style anymore. You might keep it in your closet as a memory, but you don’t wear it every day. That’s what an ex can be, something that was once important but isn’t part of your daily life now.
