Forgiving for peace holding onto a grudge doesn't empower you it controls you because all you want to do is create scenario of things that never happened. Things you want to say or could say but if the confrontation happen nothing would be said.
Using your imagination playing with hypothetical situations. You think you have the person figured out but you don't know what they feel or going through trying to get the upper hand thinking you know to find out you have no clue.
It's okay to be wrong it will bring shame you'll feel embarrassed. Everyone makes mistakes just learn from it be a big and better person for next time if there is a next time.
