And he needs a swift kick in the ass or head. He's being way too superficial, let's see how he does giving birth and nursing a kid. Pfft.

Try exercising together. Apparently it can lead to more physical intimacy in couples that are lacking. Exercising even before it's had any real effects physically can stimulate you mentally helping you feel more confident because you've done something good for your body. I'm guessing if you need a tummy tuck he does too which means it'll be good for him mentally also. Also that was way rude of him and that's definitely not the only way to fix the relationship. In fact long-term I'm sure that would not fix the relationship. This is real life he and you will both get old and ugly and if you don't learn to get past that you're going to be unhappy.

The choice is up to you, but if I were you, I would seriously consider leaving him. What does he bring to this relationship? Does it weigh up to the sheer lack of respect and common sense he’s showing off?

To save your marriage (if you even want to after that stupid sentence), you’ll need marriage counseling.

I don't know why people don't think about these things before they have kids. They destroy your body, obviously.

This marriage wouldn't be worth saving for me because I don't want to be with somebody who can only love me if I meet his physical appearance expectations. It's up to you if you feel differently.

Yeah, we'd be done......He can kick rocks

Divorce him now. Secure child support.

Does he have a 6 pack and look like a model?

Wow! The mother of his child and he acts like that!? Saying that is unforgivable! What did he give you for Christmas a gym membership? Or maybe a Peloton? I’m a guy & that is a total dick move. I’m guessing he looks like a GQ model/Adonis right? He is way out of line. If that’s how he feels, you’ll be better without him in my opinion.
