Great read about obsession out there right now is "Gone Girl" by Gillian Flynn, if anyone ever has any free time, LOL. It's fiction, but very, very, good. I could not put it down. Jodi Arias: she tried to be submissive, the good girl who would do anything her man asked, or required. She pulled out all the stops to nab him, and failed. She had to admit she had been used. No matter how much she tells us and herself that she was "helping" Travis de-stress. She was just trying to help herself, feel loved, feel needed, feel useful, and when she saw he did NOT need her , she became enraged. She planned it yes, but in all her emotion, she was surely not operating on all cylinders. No one can, under extreme emotion. She lost it, big time. When all of this is over, she will probably split into fragments and have a big time breakdown........then again, look at Jeffrey MacDonald, still whining after all these years, despite the evidence. In the end, a good submissive would have given up, and gone quietly away, weeping, all the while believing that her Dominant knows best, and accepting it. She went over the edge, into madness....and remains there.
Just my two cents....and you know what that's worth.
