you can't both forgive and forget it's either just forget it even happened and forgive them
one can never forget what happened.. even if you try to distract yourself from thinking it. the best resolution is just to forgive. it's like if someone murdered your i dunno dog,you will in the end have to forgive them. Because if you held a grudge against them for the rest of your life the reason for the hate just doesn't matter any more even if it did hurt you emotionally.
your meant to grow and learn!.. what's the purpose of life then? to hold grudges against people for the rest of your life for something that happened when you were a still adolencent is just illogical... but then again.. you'll always remember that event occured.. even if you try in everyway to forget it - remember the person involved will always hold that burden upon their shoulders for the rest of their life aswell as yours
