I am a nanny. As a live-in I have become very close to the mother. She is like a best friend to me. But, I hardly know the father who is always on "business trips." I will spare everyone the details but I know for a fact the father is cheating on the mother. It bothers me so much that I think about leaving the job! It's killing me not telling the mother. Should I tell the mother and stay or not say anything and find another job?
