Husband too critical of what I eat.

J
So I'm 21w pregnant lost about 10lbs so far. But my husband has been on my ass about what I eat. I get sick all the time. I eat very healthy and there are times where I snack on junk food but come one it's not my whole diet...he is like you better watch your munching....it hurt so bad how he said it to me. Then he was just a jerk once he saw me break down and cry over it. Why is he so mean?
