Sister asked me if I’d be ok with her dating our brother after he comes out of jail

I had no idea she even felt that way about him. I feel so lost and pretty angry. I don’t know what to say, how would I feel about that ?<br><br><br>EDIT: if this sub is going to be used to bash people who are into incest, let me make this clear: incest is not something anyone chooses. It is inbuilt, just like heterosexuality or homosexuality. Everyone has different levels of sexual and romantic attraction in a family or out of a family. In most cases, being attracted to a family member does not mean that the attraction will be acted upon. If you want to tell your story, please do, you will be listened to and heard and respected. There no judgement here. You ARE NOT alone in this. In fact, many people share your feelings.
