Always take the high road. You may be stepped on, crushed and even heart broken but at least you can look yourself in the mirror everyday and say I did the right thing, and I'm not going hate myself for it.
When someone gossips about you, it's possible that they have some resentment towards you but do not have the courage to confront you face to face on the matter. It is also possible that the person is jealous. :) It's never a bad reflection on you ever!
