My girlfriend insisted on cooking for me, which I agreed to until I saw her use a plastic cooking spoon to flip tortilla wedges in hot oil… Now the spoon is ruined, and she still wants to use the cooking oil even though it's probably carcinogenic at this point.
I have Crohn's disease, so I'm already vulnerable to stomach and intestinal cancers. How can I tell her that I don't want to eat her food without an argument?
