Getting rid of baby fat!?

So I'm a little nervous about gaining too much weight while pregnant and not being able to get my body back. Idk of any of you girls are with with a man like this but my husband has always liked me being skinny and said that if I ever got fat than he will divorce me... He's always saying you better not get fat. I'm barely 93 pounds and he already thinks I'm getting fat. He understand gaining weight while pregnant but wants me to get rid of the fat after I have the baby...I need advice!!!😭😭😭
