How do you write down what you never got to say to an ex?
Writing down what you never got to say, often as a letter you do not send, is one of the simplest ways to quiet a conversation that keeps running in your head. It works best when it is written for you rather than for them: honest rather than persuasive, specific rather than dramatic, and covering what you are grateful for and what you regret, not only what you are angry about. Whether you ever send it is a separate decision, and usually the answer is no.

Write it for yourself
The moment you imagine the other person reading it, the writing changes. You start arguing, defending, or trying to be understood. A letter that will not be sent can do something different: say plainly what happened and how it felt.
It can help to begin with a single sentence you have been rehearsing for months, and then keep going past it.
What to put in
Specific moments rather than general complaints. What you wish you had said at the time. What you appreciated, even if it is hard to admit. What you regret doing yourself. What you want for your own life now.
The mix matters. A letter that is only anger tends to keep the anger going. One that holds the whole picture tends to let it settle.
What to leave out
Questions only they can answer, such as why they did something, tend to go in circles on the page. Note them if you need to, then set them aside. The same goes for long arguments about who was right.
You are not building a case. You are putting something down.
Afterwards
Read it once a few days later and notice what has changed. Some people keep the letter, some destroy it, and some rewrite it months later and find it has become much shorter.
If you are considering actually sending something, wait. Write a second, much shorter version, and ask what you hope will happen when they read it. If the honest answer depends on how they respond, it is usually better kept.

A structured version of this exercise: a private, long-form questionnaire about a relationship that has ended, section by section, ending with a stretch about you rather than about them.
A note on safety
If contacting an ex could put you at risk, or there is a no-contact arrangement in place, keep what you write to yourself. The National Domestic Violence Hotline is 1-800-799-7233 or thehotline.org if you need support.
