because she isn't logical or thoughtful person. She is emotional and biased and has lots of irrational insane beliefs.

I dated a woman once who told me eating cereal was unmanly and pathetic. Like granola. I was suppose to eat MEAT and BREAD, and be a MAN. but eating a bowl of fruits, nuts, and grains was WEAK.

I just laughed and tried to dismiss it, but she was dead serious and basically said if I want to keep seeing her I'm not allowed to eat granola as a cereal in a bowl w/milk... only in bar form as a hiking snack or something. It was so arbitrary and bizarre.

Maybe she thought you're bi, apparently that's a big turn off for some women.
