I think to say the "rhetoric" of IM being the only source is getting old is ridiculous. it's a very valid observation. IMs statements are inconsistant, yet it's ALL we have. I can completely understand IM being distraught and making mistakes, but I also understand she's a lawyer, and a smart woman. if she can't provide consiststant information she should hire a spokesperson to speak on the families behalf to eliminate these issues.
I don't think there RM would have needed to make noticeable changes in life for him to have been talking to/thinking about someone else. just as not everyone would respond to a dropped call the same, not everyone reacts the same way when starting new relationships. as for the car, he might have loved his car, but to believe it MUST have been foul play, because he left his beloved CAR behind, at a train station he didn't like... you'd have to believe he loved the car more than his children. if a man is willing to walk out on his family, then he's prolly willing to walk away from his vehicle too.
I feel like certain people are taking this case too personally, considering no one knows all the details I don't think it's fair to discount anyone's theories, somewhere in all of this, the truth has been discussed. only time will tell which truth it was, til then every theory is equally possible.
