I'm going to put "would prefer a woman who can cook" in my dating profile
Why would you do that? What's wrong with a woman who can't cook?
I like a woman who can cook, and I don't want to spend the rest of my life with a woman who can't.
You can have things you prefer in a partner. But if cooking's that important to you, cook for yourself.
No need to keep dating a girl if she doesn't do things I like.
You should be careful about disregarding a person just because of one thing. This person could be perfect for you in every way but because she can't cook, you might lose out on her.
