It's an extremely useful article.
A good friend of mine was in a terribly abusive relationship - with her husband of 20+ years.
I'd known her for years, but I never knew quite how bad he was - until he was arrested for viewing online child abuse images. Dawn raid by police.
Turned out he had been emotionally, sexually and financially abusive to her for years - the only thing he didn't do was hit here, and because of that he held himself up as some sort non-violent paragon of virtue 
Anyway - to cut a v long story short - he is now serving a prison sentence for raping her.
Yet somehow,he has managed to continue to harass her, and abuse her from his prison cell. Via lawyers (he's not allowed to contact her directly). Via her solicitor - he makes a fuss about everything - their dc, their divorce, the financial settlement - everything. Appeals every court decision. Says he is innocent of rape, and will overturn his conviction and have her prosecuted for perjury and take the children. He is a very. very angry man. He has to win - he won't stop. He won't leave her alone.
Believe it or not, he frightens Judges and the police. I've seen it. I've been in court with her. I imagine he tries to intimidate prison/parole officers too. He's v well educated, (Oxbridge) and gets very angry about "his rights". He's the most horrific example of a narcissistic bully.
Sorry for the long post. I'm going to send article this to her.
