I think "victims" (and we don't know if she is a victim here or not) are often painted with a rainbow brush and no one can believe they would ever have done anything wrong. It's natural to do this, I guess, because it always always seems to happen.
In this case the victim is painted by a rather dark brush and not always consistent. Look at GR's story. First we are informed that he wanted to end the marriage and she begged him to stay. Note, how it puts him into the position of power and control. He decides about ending of the relationship with Jennifer and then he is begged. Not asked, talked into, or persuaded, but BEGGED. Begging side is a submissive one, leaving all the decision in the hands of a begged side - the master.
And then, aut of the blue, everything changes, and a submissive woman, who was begging her husband to stay, who spent her time caring for her family, turns completely selfish and takes the control and concocts the plan to dump not only her husband, but also her children. Remind you, she was so desperate to keep the family in one piece she was BEGGING her husband to stay, now dumps that precious family with a cold premeditation and without an afterthought. Total, utter and complete lack of consistency here.
That lack of consistence appears also in the other part of the story. Take, for instance, her preparations to leave. She gives herself a new haircut and dyes her hair to change her appearance, to make the seach for her more difficult, that's what is suggested to us. Yet she does it when her husband is at home and can see her in any moment. More, she even doesn't try to remove the traces of procedure, leaving her hair and te remnants of dye in the bathroom. No consistency here too.
Then, looking at this coiffure problem for a bit longer. We are suggested she went straight into the arms of a lover, met online. Yet we are also told she administered herself a hasty haircut in her own bathroom (hasty, because two hours is not that much of time to dye, wash, cut and comb your hair, then to dress yourself and prepare ready to leave). That stinks with some hairdressing disaster, really. How many women, ready to jump into the arms of their lover would make their looks WORSE than usual?
Then the phone. She goes to meet her lover, yet she throws away the only mean of communication with him at the very beginning of her journey.. If she did not have the other, secretly bought phone, that is just stupid.
But maybe Jennifer was kidnapped by some predator, disguised as a lover, and it was him, who dumped her phone? But then why didn't he destroyed a device full of evidence, that could lead to him? We were told she used her iphone to communicate with her online friends, so if it was some predator, why leave the evidence behind? Why not to destroy the phone, hide it where it won't be found, or just pop into a creek or a pond?
But if I was a husband, who made his wife dissapear, and if I wanted to convince everyone that she left me for an internet lover, then yes, I would place the phone carefully somewhere it would be more or less safe, and then, equally carefully, I would orchestrate a big finding scene, so the police would be able to retrieve the history of the internet chats of my wife...
