Is it normal to keep your ex-boyfriend's letters?
Mostly.Normal for most people
Yes, it’s normal to keep letters from an ex. They can matter as memories or reminders of a chapter in your life, without meaning you want the relationship back.
Lots of people keep letters, cards, or other little reminders from past relationships. They may feel meaningful because of what you shared, or simply because they’re part of your history.
Keeping them doesn’t automatically mean you’re still hung up on your ex. If seeing them feels painful or keeps you stuck, you can put them away, reread them less, or let them go—but you don’t have to toss them just to prove you’ve moved on.
