I think forgiveness means reconciliation. You agree to work together and be together, but you won’t forget, either.
What I think one can do is “letting go.” You don’t have true reconciliation and won’t renew your relationship, but you agree to let God work it out and you agree to yourself you won’t initiate hostilities toward this person who wronged you.
Sometimes you can most “hurt” someone by simply not being there to help, where you once could have been there.
Sometimes bad people need to hit rock bottom. You don’t have to fix everyone around you.
A person close to you who betrays you must still be forgiven, right? But, as you can imagine, going up to them and saying, I forgive you for this and such bad thing you did to me, is ever so likely to go over like a lead balloon. So, a better practice is to forgive the person, to commence praying for them, specifically by name, and, should you have occasion as time goes on to interact with that person (it’s presumed that you may have been forced to limit such interactions, even more or less eliminate those interactions which are discretionary), to behave toward that person in such a way as to cause them to think: I’ve been forgiven!
Charity gives us a way out of resentment and injustices.
Saints look at their neighbors from the perspective of Heaven.

St. Thomas More
Why should I now hate one for a while, who shall hereafter love me forever more, and why should I be now then an enemy to him with whom I shall in time be coupled in eternal friendship?
But on the other side, if he will continue to be wicked, and be damned, then is there such an outrageous eternal sorrow before this poor man, that I may think myself a deadly cruel wretch if I would not now pity his pain, than malign his person?
Almighty God, have mercy on __n__ and __n__, and on all that bear me evil will and would harm me, have mercy on them, and by such easy and tender and merciful means as thee can best devise, grant that their faults and mine may both be amended and redressed, and make us saved souls in Heaven together, where we may ever live and love together with thee and thy blessed saints.
O glorious Trinity, grant this for the sake of the bitter passion of our sweet Savior Christ.
Amen.
Forgiveness is for yourself, to help clear off the mental and emotional clutter. It doesn’t mean you have to invite the offender to dinner. And... no I didn’t make that up, but I have heard authoritative professionals and clergy state the same thing.
