My situation was similar to yours, hubs never gained except for a very few pounds and I kept gaining and gaining and gaining. And he NEVER had a clue how hard it was for me to lose. I hid a lot of my eating from him, being a stay-home mom for about 12 years, it was easy. I used to think that if I only ate what I ate in front of him, I would be a rail. He resented me gaining so much weight and it was a factor in our breakup, although by far not the major one. It is good that he is trying to be supportive, but you can't expect him to ever really "get it", just like you wouldn't be able to if he had another addiction. I am so amazed now that I can be around people eating anything at all and it truly doesn't bother me. That is one of the greatest gifts of this WOE for me.

Take care, keep up the good fight
