Betrayal

I suppose one can never be too surprised when betrayal rears its infamous head but, it seems that every time it does I'm never prepared! Why should I have to deal with this type of injustice? Someone should come up with a salve that soothes the wounds of a betrayed soul. The only feelings I have tumbling through me are hurt and bewilderment. I'm amazed that I'm not bitter! But, I worked through that a while ago and THANK GOD for it. There is no other feeling greater than that of a soul freed from the sticky hold of bitterness.
Is there a good way to work through this and still smile? Hmmm, I think I need to find a verse in the bible appropriate for this particular situation. I have determined to smile, and be polite and forgive. I will NEVER reciprocate the injustice of betrayal to this person. Life will move forward and we with it and I'm not sure I'll ever approach this person...or maybe I will after some time has passed and I'm a little more mature. God...please help. Thanks
