Thought she was my friend!

I wouldn't say a word about her, and I sure as heck would not be her friend any more or trust her. I bet your not the only one she has done this to, so just set back and watch her hang herself. people will see her for who she really is. good luck and I am sorry your friend treating you this way.

I know it hurts to think a friend would spread rumors about you. But I think the best thing to do is confront the friend, not spread their secrets around. That would put you in the same class as the friend. When you hear the rumor from other's lips, tell the truth, but withhold any information you have about your friend. I know our normal reaction is to do the same to the other person as they have done to us,but what purpose does it serve other than to make us feel better momentarily?

You answered your own question. You are very wise. Always rise above and don't stoop to get even with someone who doesn't deserve your friendship. If you are worried that this "friend" might hurt someone else the same as she did to you, find a way to caution them without saying exactly what happened. Instead of accusing her of spreading rumours, you could say_ "I used to be her friend_ be careful what you say to her." I'm sure you'll find your own words to stop this person from hurting others.

You should take the high road because the only thing you will accomplish by telling some of this person's secrets is to make yourself look equally bad. Refute the rumors when you can and, if possible, talk to this person to see if you can find out what her problem is and put an end to the situation. She's not much of a friend.
