Wow, if this diet (or WOL) is hard for you. Your husband is not helping.
I would ask, WHY did you give me something that I can't have. Are you trying to "kill me" If you tell him that you think that this WOL will help you live to see your children grow up, ask him to show you studies that say it is bad for you. I don't think he will find them.
You have to do what is wight for YOU
Not what is right for HIM.

Do what is right for you AND your kids.
