Interesting....Coming from a fellow male with lifelong shyness and 20 years of diagnosed SA, I think it's always easy to make gross generalizations and blame whoever you want. And as much as I love to do so:
:, I also know the tendency of persons with SA to want to predict the future without letting things play out. I've done so most of my life in order to save my fragile ego from further damage I'm sure it will endure.
I think there is some truth in what you've each said, and if you take a step back when looking at the big picture you realize a couple things: A)no one really knows what the other sex wants. That's why the book "Men are from Mars, Women are from Venus" was such a hit. The sexes are different, in addition to individuals from each sex being different. And B) because of this, women do like both nice men and bad boys. It might be due to a variety of factors, and it might always weigh towards the bad boys with certain cultures and groups, but it still varies overall IMO.
Bad boys: I've talked with and read about countless women who continually end up with the bad boys. I think at a younger age it's common due to the alpha males seeking out the most attractive or possibly susceptible girls. Later on, it might be the "damaged" girls who have been through abuse and continue to seek out similar males without even knowing it.
Nice guys: On the other hand, I know many nice guys who have found a great woman. Sometimes, this is due to the guy being very outgoing while still being kind-hearted. Other times, it's later in life after the woman has been through the whole "bad boy" relationship, and sees the type of man she really wants. Or maybe it's two college students getting together, where the man has a high respect for women and the woman has high respect for herself. Regardless, I think it's too easy to make it an all or nothing issue.
Perhaps, it's easier for a woman to find a nice guy at certain times in her life, either previous to or subsequent to any heartbreak she's had. Bottom line, I think most women want to find a nice guy and be treated well. It's just a matter of the outgoing nice guys and outgoing *******s finding them first in most cases. When you suffer from SA and aren't out there all the time and in the dating game, we're left to wait around and hope we're there when the dust settles. At least that's often the case.
