Excuses for not Forgiving:
*Revenge (I enjoy hating him/her)
*Anger (I'm too accept to forgive)
*Jealousy (I can't let him do this)
*Fear (I'll be hurt again)
*Pride (I was right; he was wrong)
*Emotion (I don't feel like forgiving)
*Self-righteousness (He doesn't deserve it)
*Guilt (I can't even forgive myself)
*Suffering (I'm just too hurt to forgive)
*Worry (What if he doesn't understand?)
And lastly "I can't forgive".
