I carry my weight around my mid-section, and it can be depressing to just look fatter, not pregnant, haha, I think there's lots of women who understand that, even if they are of ideal weight. It's like anything, we see gorgeous women in magazines and on TV with the pregnancy "glow" but that's not the reality for most of us. My face is red, I'm sweaty, and I have acne. That's my pregnancy "glow".It sucks and feels unfair that other women get to have these amazing pregnancies with these cute little bumps, but trust me, that's just your perception, every woman I have ever spoken to has body insecurities while pregnant.
Most guys are just kind of a$sholes anyways, he probably felt pretty stupid for making that dumb joke. It doesn't sound like he meant to hurt your feelings. Although, I was once told by a 6 year old that I had a fat belly (and I was not pregnant at the time) and I cried about it, so I def. hear your pain!
