Is it strange that I get mad when my husband eats gluten around me?
Why are you mad about your husband eating gluten?
I'm sick of his behavior, if he wants to ruin his health, he can do it on his own
You should not be mad at your husband because of what he chooses to eat. It's insulting that you would expect him to change his diet to match yours. Instead, you should respect his food choices as you want him to respect yours.
I'm mad about it and I'm going to say something about it tomorrow.
You shouldn't expect your husband to agree with and follow your own diet plans. Telling him that you don't want him to eat gluten will make you seem controlling and selfish. Instead, you should respect his food choices.
