I can only imagine how difficult this was for you to discover! I agree with the other posters who recommended speaking with your school counselor. Hopefully, he/she will be able to guide you through to a better position.

I don't think that talking with your mom would be the best move for you, as that would bring up a lot of intense emotions for both of you! Maybe a discussion with your dad would be more comfortable, but I would advise talking with the school counselor first. You shouldn't be stuck in the middle & trying to resolve the issue.

Please reach out for professional help now. The longer that this issue sits, untalked about, the longer your suffering. That's where resentment grows. I wish you the very best in getting some help in working through these emotions and finding the best technique in your dad finding out the truth.

Very best wishes to you and your family!
