The problem with people telling you to "move on" is the consequence of liberating them of their unatoned transgressions.
The reason a court does not "move on" or advise the victim's family to do so is so not to embolden the guilty to repeat their crimes with impunity.
If telling someone they're only hurting themselves when they keep their assailants' sins on the table, why not the assailant advance the same "let it go" advice to their victim, even ahead of the next intended injury, since it's only a matter of time before that future offense will be in the timeline's past also, right?
Do you understand the absurdity?
"I shall hurt you tomorrow, but eventually tomorrow will become yesterday. Therefore why should I apologize for, or even refrain from, what I'm plotting against you when, instead, I can just bid my time and later pontificate to you how you should get over it already because the past is the past?"
