I agree with that saying...but...forgiving is forgetting. (Obviously we must avoid the same situations in future)
Forgiving is forgiving , and forgetting is something else.
See, the person we forgive, might just be a clever devil.....and now that they are CAUGHT, they are "oh so sorry and just cry and repent and
beg you for forgiveness".......until they do it to you again, or to the next victim.
So, forgive and keep your eyes open..
Now, if you are dealing with a family member, then that is a different situation, but its also not., as of course we are going to try to deal with our own BLOOD in a way that is extra grace inspired......but even then, sometimes someone in a family is just hell bent on being hell bent, and so you sometime have to eject them from your existence......tho forgiven.........and you are not going to forget.
