He body shames the pregnant me

I am 13/6 weeks and my fiance won't let me eat. I have terrible hunger pangs and he reminds me of how big i will be after the pregnancy of I don't manage the way I eat as he keeps reminding me of how fat I am and how his friends keep telling him that i'm growing big (we haven't announced to them yet). I had a banana and yogurt the other at around midnight and he shouted at me for eating while lying on the bed saying it's unhealthy. I was told that I need to also manage my unhealthy cravings, which is hard during pregnancy. Okay, i'm done venting, thanks for listening😊
