Have you told your wife her comments are hurtful??? As for you feeling like you don't deserve her ......can you identify any specific reasons? Are you feeling good about yourself in other aspects of your life? Or maybe your feeling bad overall.. I would suggest maybe see a Therapist, that would allow you to look at your relationships and self worth and find ways to feel better.

Seriously, talk to your wife about her making such comments, as Chippermonkey said Everybody looks... No need to make comments.

Hope your feeling better soon. Welcome to PC
