Today my boyfriend and I were cuddling in bed together without our shirts on, and he couldn't help but feel self conscious about his teeny tiny belly. He texted me later this evening that he's sorry if I got shocked by his 'fatness' and he hopes that he can be better for me. I just feel sick to my stomach, I can't seems to prove to him that there's nothing wrong and that weight doesn't matter. Any tips or advice?
