There is no need to repair any relationships that have hurt you.

Those who hurt you did so intentionally.
There are no unintentional mistakes, only choices made after weighing the options.
So, even if the other person turns back and shows kindness,
don't rush to forgive.
Otherwise, all the grievances you've suffered will be considered deserved.
Remember these words:
You can choose not to hold a grudge,
but you cannot forget lessons learned.
You can generously forgive others,
but you should not foolishly trust others again.
