There are a few books written about this:
The bad boys end up getting a lot of girls because he can take her on this ride up and down, that is sometimes a lot like a drug. unfortunately a lot of the times these men are physically abusive.
On the other hand, it also showed that most women end up marrying the nice guy, and being for the most part happy with him.
If you ever want to strike up a conversation with a girl and don't know how, hang out around the romance novel section at the bookstore. when you see a girl browsing the area that you want to talk to, approach her and say that you heard these romance novels were really popular, but you've never read one and were just wondering what some of her favorite ones are and why.. cause you'd like a suggestion.
