Forgiving someone doesn’t make what they did okay. It makes your future stop paying their bill.

Two separate questions get tangled together: whether something was wrong, and whether you keep carrying it. Releasing the second does not answer the first in anyone’s favor. What happened stays exactly as wrong as it was, and the only thing that changes is how much of your remaining attention it gets to take.

If this is live for you, there is no schedule you have to meet. When and if you are ready, try noticing how often the thing still runs in your head, and what it costs there. Letting go of the cost is allowed even when nothing has been apologized for.
