You will grow better when you focus on the lessons in life opposed to the hurt. Sometimes you may not receive the apology you deserve, but dwelling on that pain will only lead you towards suffering. So accept the apology you’ve never heard and forgive. Forgiveness is not for the one doing the hurting but instead for the one hurting. Inner Peace is the new success and Happiness is the new rich. So leave the past in the past and move on for the sake of your own well being.
