It could be guilt and fear on his part, and he may not even realize it. My sweet husband is outwardly supportive but the minute I begin to look more attractive, he starts with the "Just take one bite - it won't hurt you." Oh but it will hurt me, psychologically and physically. After 23 years, I know he loves me deeply and knows I love him deeply, but men are, after all, pretty insecure. Also, he could stand to lose a few pounds, and he feels guilty when I do and he doesn't. I understand that because it was the other way around earlier this year.
