I'm talkin to the wormen here

ok well I must say that it's not only the girls who go for the @ssholes. I have a lot of guy friends who date girls who just don't care about them and use them just for show and tell. I have no idea why these great guys still put up with it when there are so many other girls out there who are really great people. These guys will do anything to keep the girl happy even though she only uses them... please explain why you guys go for these girls?
But for the guys defense I did find this little letter that might add to the topic of discussion... http://www.angelfire.com/vt2/g_hols/Niceguy
