systematically destroying everyone involved?

My niece who is 4 yrs younger than me is a pain in the ass. really. I love her but she is high maintenance. I believe she has a wiring issue and needs help.

Ok. so my h acted out in lots of ways, but particularly on golf weekend with his brother and my nieces husband. According to my h, my nieces husband always walked up to the line but never crossed it. (what ever the hell that means?). The jolly brothers fucked whatever they could. (no need for condoms ~ these were nice girls).
Anyway, since all of my h’s shit hit the fan and lots more was exposed, my niece has now claimed that my h has made hundreds of passes at her, starting when she was 14. She now claims he is an evil pedophile. That what he did has terrorized her for her whole life and she has had trouble dealing with it. She wont say what happened specifically. My h denies all of it. He gets wild when I try to talk about it, even in front of the csat. She did not show up on the polygraph test as one of the under 18 year olds. He passed the test. Hard to know here, like I said she is a pain in the ass, loves to be a victim in every situation, she is nuts really. (cannot imagine why he would mess with that hornets nest ever!)

So…..more stupid drama….. The other day on facebook, my niece and my brother in law (jolly fucking brother) and his wife ~ who has forgiven him completely ~ were all messaging each other. It was all fun, haha banter back and forth. Well it made me incredibly sad. I am no part of my old life anymore. I ran/walked 10.5 miles and came home and unfriended the whole bunch of them. problem solved. I can’t see it, it makes me feel sick.
Well my niece went ballistic on me and sent some really terrible emails for “excluding her”. I told her I miss my old life and it makes me sad when I see it. I need to protect myself for a while. And for cry-yie its only face book!
no, she turned this into a vendetta against her and her family. So enough email I called her. it was ugly. I did not hold back. She kept grabbing for reasons to make this about her (martyr). SOOO she brought my h into it, and how abused she was. Still wont say what he did, but I’m pretty sure he played footsie with her several times. SO I flipped my wig and said that I am sorry for any thing bad that happened to her. BUT this is between her and my h. NO ONE told me. I would have done something about it 30,25,20,15,10,2 years ago if I knew. I did not know, therefore this has nothing to do with me! No one gave me the option and its not fair to dump it on me now!

Am I right?

She wants sympathy from me when, She claims to have known he was a pig for 30 years (it never stopped her from hanging out with us though or having us watch her kids!), Her husband has been with him while he was acting out for at least 8 years. she just found that out. I think her husband is a pig for going along every year. I don’t blame him, but I also don’t like him anymore. I’m allowed to feel ripped off! right?

Scary thing, I think she recorded our phone convo. SHe is weird like that. I didn’t say anything I regret. but I am wondering if she is going to try to sue him somehow. she loves to litigate. Is it even possible?
what a mess.
