Please define "nice guy" ! My sweetheart is a nice guy. If he wasn't, he would have never had a chance with me in the first place. But then again, what is a "nice guy"? Just because a man isn't mean nor hits women, doesn't automatically make him a nice guy.
"Nice guy", the dude you are friends with, but would never date. "Nice guy", the one you always talk to, but he ain't bad enough...There are many different examples...But he doesn't have the edge..
I used to be a nice guy..but I slowly learned the cold hard truth, I had to have my head bumped a couple of times...
I had always noticed that I got more attention from the womenfolk when I was smart ass, with witty, yet harmless wisecracks, than when I was a "gentleman", who women would say that I would make the perfect husband (attentive, caring, flowers, ugh

).
