The logic is similar to the old idiom: If you have to say you are a lady, you are not a lady. With dating, you have be sought after, and not chase after others.

Remember that being a real man is not the opposite of being a woman, but rather in not being a child.
"Unfortunately, she was looking for the perfect man."
In my experience, an overlooked part of finding a good mate is making yourself into a good candidate for your side of that partnership.
