This makes me sad too. I don't really hate the author, I just feel sympathy. Unless she's being really sneaky and pouring cream into his skim milk, he's a grown man and can make his own choices.
I do hate "fat logic" and the self-victimization that usually accompanies being overweight, but I always feel sorry for these people. I cannot fathom how it must feel to have so little self worth, to try to lose weight again and again only to fail. None of us would ever let ourselves get to the point of being obese, but I seriously can't imagine trying to bounce back from that. I understand how easy it must be for these people to throw their hands up and say "Why bother." I hope this chick gets her shit together, and I hope her boyfriend exercises some autonomy over his own eating situation.
