I hope you kicked him firmly on his behind and said "I liked you better when I was fat too."
I haven't lost all the weight yet but I do anticipate some changes, I don't know what it will be but of course things will be different. The mature thing is to sit down and talk about things before he comes out and says something so nasty. Now there are hurt feelings involved. But you can't skip out on it, you have no choice but to sit and talk it through - find out what it is that's changed for him? Is it the amount of time you're spending away from him? Is it the jealousy he feels of being more attractive to others? Does he miss his fatty enchiladas? What is it that he finds so intolerable about the changes you've made? I can't imagine that he loves you because you like to drink wine and cook fattening meals. Please let us know what happens when you sit and talk to him.
