If you haven't already told her you might want to tell her about how you felt about getting and being fat. Some times blunt honesty is the best.
True story: A long time ago my x was dead set that she needed a boob job. She has a 32b and I could not love them more. But since the girls in playboy and on tv (none of which I like) had big boobs the just assumed that that is what I really wanted and would leave her sooner or later for a big set of tits. Well I got sick of hearing about it since I would never do that. I sat her own and got out my porn stash. Over half of it was just pic that I had of her and stuff, the other half was of girls that looked physicaly just like her. We had a long talk and it came down to if you want biger boobs for your self I will suport you, but if you want them to please me you are going in the wrong fucking direction.
Yes that was blunt, but it worked.
Another thing that worked. She has put on some weight, but in all the right places. Well she claims she is getting fat. Well I just reply, "you arn't but this is." And then I poke her with my hardon that poped up in the 30 seconds she was looking at her ass in the miror. Now she does that just to get a rise out of me.
