Male Psyche on Dating

I have learned a little bit more about the male psyche as it pertains to dating.

1. Guys are passive because they don't want to be rejected/low self confidence/shy/etc (yes, we have gone over this 1,000 times)
2. Guys might enjoy not knowing and holding on to the hope more than knowing what is really happening (explanation: "Well, I am not going to ask her out or suggest we do something because I can keep believing she has a crush on me until she tells me otherwise"
3. Guys don't like to get too excited about a girl because putting themselves together would be much more difficult if she does not return the interest
