A hug? You got it. Sending lots and lots of cyberhugs your way....
I'm in agreement with the others. Weight loss/gain/maintenance is a PERSONAL experience. This has nothing, nothing to do with your husband. This doesn't sound supportive, it sounds humiliating. I would tell him that this is something you need to do for yourself. Yes, his support and ENCOURAGEMENT are one thing, you don't need him monitoring your every move. This is your issue and you need to deal with it. Not deal with it - AND him.
1200 calories for a week? You've been struggling for sometime now, haven't you? You've been struggling with a higher calorie allotment and haven't consistently met that. Therefore, I really don't see how LOWERING your allotment is going to be something you can (or should) do.
You need to find/make/devise a plan. One that you are WILLING to stick to. Day in and day out. Perhaps you'd be better off in different type situation. Maybe a WW type thing. Where you go to meetings and get support from other like-minded people. Or maybe speak with a nutritionist or dietician. They can guide you as to what to eat and what not to eat, help you with the planning and menus. It would also be someone to hold you accountable and would be looking out for your best interests. Your own personal coach.
There is something out there for you. Keep on searching and delving. Because it's there. Don't stop till you find it. Be open to it.
