Erin,

You're in a difficult position. I think that it would be a good thing that you tell your father what you know and how it's making you feel. Then again, he might not be too happy that you know things that were meant to be kept a secret. I would also talk to your mom as well. Get her opinion on it. It might help you a bit. But either way, it's ALWAYS good to let people know how you are feeling. If you don't like the woman your father is marrying, then you should tell him. Give him reasons as to why you don't like her. I know you want your dad to be happy, so maybe you can compromise? You can try and get to know his fiance. Try to look for the good qualities in here, rather than focusing on the things you don't like about her. Your dad loves her, so there has to be something good there.
