So a few years ago I mentioned to my wife, i would like her to gain weight. She seemed to be ok with it. She grew in size i even got to feed her once and she liked it. Now she is bigger than ever and she wont let me feed her or mention it. She also doesnt let me look at her when she is naked. Im always telling her how sexy she is, and she says she isnt. Basically i need some advice on how to make her believe me when i tell her she is sexy, be more confident in herself and later try to bring up feeding.

What chubbyhoney said.

While it's fine that you show her that you appreciate it/she's still sexy to you. Don't use it as a way to change her mind.

Support her in what she wants to do, be it maintaining or losing weight. And make sure she knows that, else any and all appreciation/support will feel like manipulation to her.
