You will never be able to end any battle if the people involved are unable to see their own hypocrisy, or how their insecurity contributed to their problems. Wounded people often choose to play the victim, so they can restore their dignity in unhealthy ways. Sadly, they do this through feeling justified, by making bad choices or actions (that honestly no diety would want them to do). This inability to accept their part in their unhappiness keeps them from growing. They need your prayers more than your anger. Just walk away. Let it go and pray that one day they will understand your pain, as much as you do theirs. Remember: The sexiest woman alive is one that can walk away from a place that God doesn't want them to be. Do so with your head held high and forgive yourself and others. When you can do this, you will know what God's definition of class is-- YOU!
Everyone loses their class when they travel through hell, but only a few will regain it if they remain humble and accept the part they played in their own misery.
