For me, it's my bf. A lot of it is he was scared (and still is) about the surgery itself and the aftermath. Then he seems to have a chubby fetish (which he only seemed to acquire or bring out into the open) when I started talking about surgery. Post-surgery...he barely talks to me, barely touches me, rarely says anything nice (and in fact, told me he missed my missing stomach). He makes me understand why so few relationships survive this surgery
So yes, I understand having someone completely unsupportive. Luckily, the rest of my family is incredibly supportive and understand completely why I did this. So I try to ignore his bile and hope that he changes. If he can't accept a healthier me, then much as it hurts to say, he doesn't deserve me.
