Husband made me feel bad about myself

Yesterday we bumped into a group of friends , one of them has a 19 monthly old baby , we have. 13 month old.

Still struggling with loosing some of my pregnancy weight.

The friend with the baby is now pretty thin ,

When we continued walking my husband all of the sudden comments how much weight she lost.

I got really sad and embarrassed :/

He always try to comment and tell me I’m beautiful , he’s not a man to put me down , it just bothers me yesterday
