Making him feel like he’s ruining the fun
“Aaaaw come on. We’re all sharing a huge pizza. You’re just getting the grilled chicken? Part of the reason people come here is for the pizza. Why did you even come here if you’re not going to eat it?” Again, social engagements don’t need to be about food. Don’t make your partner feel that he isn’t thoroughly experiencing/enjoying something if he doesn’t eat what you’re eating.
