Well if someone is talking about you your ears ring. At least they do for me! Left one for something bad, right one for something good. But usually the best course of action is to ask around. Someone is liable to give you information.
And as for the betrayal. Why are you counting your chickens before they hatch? You can't blame someone for something they haven't done yet! We all have free will to change our futures. No future is set in stone.
