How to deal with unsupportive SO?

dayswillpass

I'm very gung-ho about my weight loss, but my fiance isn't. I'm happy he believes I'm sexy the way I am but he won't understand I want to do this for ME and him sitting there telling me I'm beautiful all day isn't going to change my outlook on the situation. When I try to watch my calories/fat/whatever and tell him 'I'd rather eat -x- instead of -y-' he gets irrationally angry and threatens to block any and all sites with "calorie in the name" on our router and tells me I never listen to him. I mean, come ON. Anyone have any advice for this? It's becoming frustrating
