Have you ever dated someone who didn't like the same kind of food you do?
I once dated a guy who hated blue cheese, he couldn't be in the same room with it because he said it smelled so bad. I eat blue cheese on my salad almost every day. Needless to say, it didn't last between us.
I was also married to a guy who ate only plain foods. Tacos were ground beef only, no onions or spices whatsoever. That didn't last either.
