If you weighed in your own fault and it was “little to none” you should be at peace. Off course that can be real difficult - letting go, together with forgiving. [I say this because in the blame-game it’s a terrible trick to feel blame for what isn’t your blame (the moral dissection of any situation is always complex). (The psychological technique of “gas-lighting” is frequently associated with this.)]
Lets assume you were wronged and didn’t in turn wrong the other person.
Here comes a “big catch”: How to stop loving if we are supposed to love? Or better, how to love while stopping to feel? Better still, how to get a grip on your feelings while keeping with sound charity (love)?
Well, lets be pragmatic: It won’t change anything. [And it’s usually said: you’ll be giving a big satisfaction to the one who wronged you.] Still pragmatic: is realistically any peace to be gained from talking to them - are they even able to recognize reason or use reason?
Closure is to be found elsewhere. And it probably won’t be easy. That person holds a debt towards you, forgive that debt and any restitution. [Any understanding may simply not be possible.]
If your wound is deep, let’s assume that person caused you real harm and injure and serious loss. Because that gravity of the “good you were deprived of” would justify not being able to let go. Then you might be in a really “hard spot” between a rock and a hard place. Needing to re-equate how you go about “that good” in itself.
A very complete (and quite complex) overview&buildup is given in the following video. Yet, what you may be necessitating is something else. There is no way to know from the content of the OP.
