I am married to a man who has a problem with alcohol. He hasn't touched a drop for over 7 years now, but he had to hit rock bottom before he acknowledged that he had a problem and had to deal with it.
Yes, there is help for eating disorders, alcoholism etc, but crucially, you HAVE to accept you have a problem before that help will do you any good.
I think a previous poster made a good point about protein, up-thread. Maybe the OP's husband would do best on a high protein, low carb diet - I have a friend who is on a diet like this, and can have cream, butter, cheese etc - for example, the fry-up would be fine as long as there were no carbs (though I wouldn't put cheese on it). Protein fills you up and satisfies you.
This won't work for everyone - I couldn't cope with that diet - I do better with a bit of cutting down all across the food groups - but equally, pie and salad, whilst a perfect meal for many of us, wouldn't suit others at all.
I do wonder if this man has a genuine addictive disorder - it would explain why he can eat the food that's for the OP's meals, without realising or understanding why that would upset her - it's the blindness of the addict. I know it's different, but when dh was still drinking, and before we realised he had a problem, we bought a really nice bottle of whisky, to share. It sat in its box on the sideboard, and I didn't realise he was drinking drams in secret, until I looked in the box one day, and the whisky was almost gone. It was intended to be a shared treat, yet he had drunk it all, without a thought for me.
The other possibility is that this is a genuinely selfish, thoughtless man - we can't know. But my heart goes out to the OP - it sounds like a horrible situation.
