Forget what hurt you and move on. Carrying that baggage will only hurt you. The person who hurt you doesn’t even remember.
You need to set and keep boundaries after forgive someone.
If you cannot take lessons from life’s failures you will never grow!
Mostly, humans don’t forget, but forgiveness removes the sting.
People who poison your spirit 
People who hurt, lied, betrayed, disappointed & broken your heart 
The only time you should look back at your past 
Never be reckless with someone else’s heart
