Why do some women say that good guys need to be patient, and that women will eventually want them?

Why not just date the good guy in the first place, instead of intentionally dating losers before you get to the good guy? Why make things difficult on yourself?what makes women think that the good guys will want them and their baggage after the bad boys have screwed them over?what makes women think they can come back to good men say 2-3 years later and use the line "Oh, I'm past that. I only date good guys now"? Seriously, why would any halfway decent guy want you after you've had sex with god knows how many men, probably have an STD or 2, and have trust issues because you chose guys that cheated on you and treated you like sh*t?The fact that a girl chooses a bad boy over me doesn't bother me. Hell they deserve each other and I certainly know that a relationship wouldn't work out anyway. The part that does bother me is her coming back to me a few years down the road, thinking I'm going to take her without a second thought and not give a flying f*ck about her past.I'm so sick of this nice guys don't ask you out bs,is that the beat lie you women can come up with?you say crap like well if you are really nice then you would accept that the girl made a mistake,No you run after the so called bad boy over and over knowing full well what the outcome will be,that's not a mistake that's stupidity.
