I see that, and I definitely think the ST article points in that direction, but I guess I see Blake's behavior as making sense on some level, Asperger's or no. I have a friend with Asperger's and if she had a boyfriend or husband with a lock box who never talked about his past, she would break that thing open as quickly as any of us. Asperger's could explain Blake not understanding that LEK's behavior was not normal, but I think he definitely knew there was a secret, at the very least because his family members would have pointed it out to him. I just think he didn't push the subject for reasons I find understandable, mainly respecting her privacy because he thought her reluctance to talk came from a place of trauma. I also think there is a certain personality type (and maybe a lot of people with Asperger's fall into this category) where you are overly rational and logical about everything and can come up with a boring, mundane explanation for any mystery you may encounter. These sorts of people often identify as skeptics; it doesn't come from a place of naiveté. I mean, plenty of people keep secrets and are estranged from their family and in 99.9% of those cases they never stole their identity from a dead child. Plenty of people do have things in their house they don't want their spouses going through, and 99.9% of those people are hiding something mundane that their spouse probably could have guessed at.
I agree with what you wrote with one exception, & that's doubtlessly due to my own error in expressing myself. I didn't to say that the ST implied Blake has Asperger's, although it's likely he does. It was that the article implied he was somehow mentally deficient, which explains why he never got her to share her history with him. Asperger's enters into it only because, from the people I've encountered who have it, it could allow him to be comfortable with not asking about her past.
In a way, Blake & Lori were a good fit. She didn't want to talk about her past; as far as she was concerned her life started the moment she met Blake. Blake found a woman who would tolerate his oddness -- & was attractive to boot. I suspect neither ever expected to be married, & for it to happen to them made it all that more special for each.
I think it also may explain the conflict with his family quite a bit. They were very protective of him and used to looking out for him as growing up he was perhaps bullied and had a harder time making friends. So when they saw him with someone who was an outsider to them, someone who acted strange and who was clearly keeping secrets, they worried LEK was out to hurt or take advantage of their son. The way you relieve your suspicions of someone is by getting to know them, and I'm sure they really did try and give her plenty of opportunities, but she couldn't handle their questions and the more they asked the more withdrawn she became. I can easily see how the situation deteriorated over time, and I think it probably wasn't anyone's fault and they all probably had good intentions.
I think LEK was just not mentally in a place where she could handle being questioned and simply thinking about her past only made her more upset. If she were a criminal and a pathological liar like a lot of the people who get discussed on this site I actually think she would have handled the situation much better. A good liar can fool people in ways LEK could not.
I've pointed out many things about this case that make it hard to understand LEK & her motivations. (For example I'd really like to know who took the initiative in that first meeting, Blake or LEK? I can envision each of them taking the first step, & I can envision neither of them taking that first step.) One is that we only get an impression of LEK of her last years, long after whatever led her to obliterate her birth name had happened, after years of living with the consequences. Was she always so private about her past? Did she always have this much trouble being close to people? Was she always so aloof? Because I have a sense that the step that ended with her downfall & suicide was a life-long character flaw: when LEK felt threatened, she couldn't help but getting critical & vicious. This may be the reason her career was limited to entry-level jobs.
I think the ST article got this detail right: by compulsively criticizing Blake's family, she drove him away. In a brief moment, she destroyed one of the major accomplishments of her life. I suspect she knew she had done this; I suspect she knew she had harmed herself by doing this many times before in her life; & I suspect that she realized she could not escape herself. That is why she lost the will to live.
Although the Ruffs were frightened of her, she was probably more scared of them than they her. They had much she never enjoyed: friends, a family, a history, a home. Her stalking of them was probably more like a poor child staring thru store windows at things she would never own, but her lack of social skills made her harmless actions creepy & threatening. When she received the divorce papers 20 December 2010, she found her last achievement -- giving life to a child -- taken from her. (So where was the daughter the last days of LEK's life -- with her, or with Blake?) She killed herself in her in-law's driveway, so to say to them "You made me do this!"
I could say more, but none of it is relevant to this. Without more evidence, I'm not sure I'm getting into her head, or just creating a character in a work of fiction.
