It is human nature to deny what makes us uncomfortable. I sure as hell do it all the time to myself about my feelings.

In your case, as in mine, people will simply deny all knowledge of something. Why ? It makes them uncomfortable being confronted about it. Actually it's very likely ! I used to quite enjoy watching my parents squirm, but i digress.

Humans do not like the "balance" upset, we will do everything we can to stop it, and it if means denying someone the truth, then in some people's opinion it is worth it.

It would appear you've hit a brick wall with that family member. If they cannot be open and honest with you, then really ? They're not worth taking to in the first place.

I know it is difficult not to feel anger and hatred towards these people, but remember they considered themselves "above" you, and likely still do.

It may not feel like it (and it usually doesn't) but you are now free from that. Consider yourself a much better person for it, by not bowing to thier lack of standards.

Stand tall, be proud. You are an individual and you are free. You are not stuck in the "fairytale" bubble that they are !
