I agree. He probably steamrollered over any opinions she might have had, which no doubt would have made her feel even worse than she already did. I see in her stance a defeated woman who has just been dealt the ultimate blow (the cancer returned) and has not been supported by the one who should be her protector and champion. She knows she is going to have to go through the worst alone and have to be strong for her children. I am so sorry for her. Money and power are no substitute for true love.
I don't know if he steamrolled her opinion. Maybe his decision to keep campaigning is just a form of denial. It might be easier to focus on running for the White House than to sit at home and face your wife's terminal illness. Regardless, I wish Mrs. Edwards the best.
Since you weren't there, nor were you a party to this decision, isn't your post a bit presumptuous?
