For what its worth, I have ran into some idiotic people in the past and cut them out of my life. I am sure they still run around and spread lies about me and my husband. Is it really worth your time to worry about this? How can you even stop this from happening? To me, if somebody listens to this persons filthy mouth, maybe they arent worth spending time with anyways. I have cut out everybody that was friends with this pathetic friend of mine at the time, and everybody that despite knowing her being a pathological liar- still lent her an ear and even considered what she said to be true. Made life so much easier and simpler. Spend your hours with the people that love you and know who you are, people that will defend your honor and not tolerate anybody bad mouthing you. Everything else is out of your control.
