Not eating enough

Savannah

Okay ladies, I'm fifteen weeks exactly as of today. My boyfriend is constantly talking about how he needs to watch what he eats, how he needs to lose weight so he'll be healthy when the baby gets here, and he's straight up not eating some days. I don't think it's good to be around. I'm already overweight and I'm already terrified of gaining anymore weight with the baby. Around him, I'm barely eating and I end up throwing up from panicking about gaining weight. I've lost at least 10lbs since I found out I was pregnant. I know it's not healthy. Around my family, I'm fine and they encourage me to eat and I feel great about it! What should I do? Opinions? I've told him how I feel in quite a few ways to try to get him to understand but the only thing I can think of is to be around him less.
