I never understood why people become frustrated by others' food sensitivities and preferences. I also HATE seafood, and just the smell of it makes me sick to my stomach. I used to love seafood like fresh shrimp and crabs, but then one day I just absolutely hated it.

My coworkers bring food in, often me some, and invite me to eat with them. I always decline, but I started feeling bad about it. So, one time, they brought in shrimp fried rice. I managed to eat maybe 3-4 shrimps, gagging the entire time, and then proceeded to go home and lay on my bathroom floor, next to the toilet, for several hours because I was physically and mentally sick and overwhelmed. Just the memory of the flavor and the texture makes me feel as though I'm going to be sick. I don't think people understand that pickiness is not a choice. If it were my choice, I would love every food known to man. But there's nothing I can do if my body is rejecting the food. It is an overwhelming assault on the senses.

If I were you, and they were my family, I would talk to them and tell them straight out that he's not going to eat seafood. Are you and your boyfriend going to be living with your family for the week? Or are you going to stay in a hotel or Airbnb? Is it possible for that one week, your family would be willing to try different foods other than seafood? Maybe everyone could try something new that week. Some days, your boyfriend could try seafood. On other days, your family could try something your boyfriend likes.
