I'm going to force my boyfriend to eat
Why do you want to force him to eat?
I want him to take interest in my food.
It's not nice to force someone to eat when they don't want to. You should let him eat whenever he wants.
He's too skinny and he eats like a bird. He needs to eat my cooking. How is this my fault?
People deserve consideration for the place they are in with regards to their weight and their eating habits. You trying to make your bf eat is forceful and disrespectful. Support your bf, don't try to control him.
