I listened to your episode about uncovering a family secret and it got me thinking even more about a family secret that I'm holding onto. My sister got pregnant years ago after basically having a one night stand. She started dating someone not long after and they decided to just pretend like the baby was his. My niece is now 10. She has no idea that the man she calls dad isn't her dad. I am sure she'll find out someday one way or another. And I can't help but worry that she will be mad at me for not telling her. I hate to keep the secret. I've asked myself what a mentally strong person would do and I don't know the answer. Please advise.
