I think to generalise, hot girls who have a problem holding any sort of eye contact or admitting interest in a guy, are subconsciously more picky than they realise. This may be you, as I've seen it with plenty of girls when you really get to the crux of their issues.
However if you were in an abusive relationship you may be somewhat scarred, this may not be permanent but I've also seen this, girls have an incredibly hard time trusting any man, hot or not, they see the potential for any person to be abusive. It's hard to shake that, but maybe the club dating stranger scene is not the place for you to be thinking of finding someone.
And where to find someone then? Well, ideally within a circle of friends, so that may take patience to find an appropriate guy. But if my suspicions that it's down to an abusive relationship are correct, then you need to find someone who knows they need to be patient with you in all ways, because that trust won't come easily.
But as you know, it's certainly not normal that if you want to find a guy, you keep brushing them off. I'm sure you must feel attracted to some of these guys, but either on some level you feel you're too good for them (and I'm not criticising here, we can't help our base instincts) or you feel you can't trust them, every guy is "not right" for some reason you can't put your finger on.
Were you always like this, before the abusive relationship?
