My husband always said he loved me just the way I was, and insisted I was not obese.
I was so obese! And I knew it! He knew I was very unhappy. He's very understanding that I need to do this for HEALTH reasons. Plus, my husband isn't "into thick women" at all...he just loves ME no matter my size.
He is having a bit of trouble with the loss of the girls, however.
I would focus on the health aspects with your husband. Curves are fine, excess fat is not. And you have to feel good in your own skin. I certainly understand that!
