Some of the good ones DO look like centerfolds, and they're STILL single.
For the men, being a "nice guy" often cancels out the advantages of height and good looks, and renders good moral character irrelevant as well. Women have the idea (sometimes right, often terribly wrong) that nice guys aren't strong, real men.
For a woman, her good looks may be her downfall: they elevate her perception of the type of man she thinks she can attract, so she'll hold out for more money, height, "coolness" (which is often inversely proportional to character), education, status, etc, than an average woman. But, alas, there aren't anywhere near enough tall, handsome multimillionaires to go around, compared to the vast number of women who think (rightly or wrongly) that they can attract one.
Fortunately, I met a woman who was smart, beautiful, AND realistic, and thus I at last escaped from the singleness trap. (Had to be from God.) But many of the women who rejected me, are still alone, and the guys they might have once been able to land, either married someone else or are now targeting a younger age bracket.
I'm aware of a couple of his ex-girlfriends who were quite beautiful and really gave him cr@p.......because they could get a away with it for a while. Hubby finally realized what was going on and got sick of their "I'm entitled to treat you like cr@p and your're required to spend lots of money on me" attitude. As he told them when he broke up with them, "Darlin' there's lots prettier girls than you, and you certainly aren't good-looking enough for me to put up with your sh*t!"
