This situation, no matter how it is calculated, is difficult to be fair. Let's eat together, AA, and there is also the question of who eats more and who doesn't eat. It's impossible for no one to complain for a long time. Your boyfriend cooks and washes dishes, and people may not think that he should eat for free. What did you say?/Sorry?

Therefore, it is recommended to eat or cook by yourself. Even if we eat together, we buy our own food and share it ourselves. We can have dinner together if we like. So nobody owes anyone. A lot less trouble.
