You can wait forever for an apology, or you can get on with your life and let it catch up if it wants.

An apology that has not come may never come, and waiting for it hands the timing of your own recovery to the person who hurt you. That is not fair and it is how it works. Moving on is not the same as saying it was fine, and it does not close the door if they ever do arrive with something real.

Decide that your life resumes now rather than at some future moment of acknowledgement. Let the hurt be true and let the calendar keep going. If the apology comes later, you can receive it then, with less riding on it.
