welcome aboard! I know what you mean with friends' comments. My fiancee in particular can be dangerous to me because, well, he's a chubby chaser and actually begs me not to become too skinny!
They mean well, though.I think people who love us just don't want us to feel bad and they are trying to reassure us that the weight doesn't keep them from loving us, however we feel about ourselves. And remember, weight is such a taboo subject. It's a very special relationship to be able to tell someone they could stand to drop some poundage.
