I saw some people discussing this on the Catholic Match forums a while back and gave the question some thought. The results are now up:

The basic version is that men are more physically oriented, women more relationally oriented. A woman typically wants to learn more about a man’s character, personality, and capabilities. Thus, what a man fundamentally looks for is signs that a woman is studying his character, trying to dig out more of his personality, and liking what she sees.

Here are some specific, simple signs you can give to let the man you’re talking to know that you’re interested in him.

1. Talk about yourself.

Sounds a little counter-intuitive, but there is a method to the myopia.

Obviously, this doesn’t mean talking non-stop about yourself, or making the relationship all about you. It means sharing your personal concerns, your ideas, and what’s going on in your life and (this is important) seeking his input and support. By talking about your own life, you signal that you want him involved in your life; that this isn’t just a means of passing the time for you, but that you want him to take an interest in you, personally.
