Saying sorry is your move. Accepting it is theirs, whenever they’re ready.

An apology is not a transaction with a guaranteed return. You can only do your half, which is saying the true thing without a defense attached to it. Treating their response as the point turns the whole thing back into something about you, and people can feel that immediately.

Say it, mean it, and do not add a question at the end. No checking whether things are fine now, no second apology three days later that is really a request. Let it sit, change what you do, and let them arrive when they arrive.
