I'm not saying that women who fall for PUA can NEVER have a sound relationship. I'm saying their head is not in a good place right now.
Also, frankly practically every woman has fallen for a PUA tactic at some point. Including me. You don't realize it for what it is right off the bat. You have to have experienced it or heard of someone else's experience so that you recognize it for what it is.
Dates are distracting by nature. You have to give someone a certain level of trust that they probably haven't earned (especially if you don't know them that well) to even go out on a date. You go with certain hopes and expectations and so do they. You're trying to be charming and also looking to charm, to someone you're already attracted to (otherwise you wouldn't have wasted your time). It's a particular atmosphere or dynamic that doesn't exist elsewhere. You get a buzz in your head and your heart and ... sometimes elsewhere, so you're distracted.
Falling for a manipulation is bound to happen some. There's a learning curve, so we can cut ourselves some slack and move on. Live and learn. Continually falling for manipulative behavior means there's a problem.
So yeah, if you were to exclude everyone who had ever fallen for manipulative behavior, most of us would be undatable forevermore. So it's good that you're not holding that against a potential date.
Out of curiosity, what did you have planned for this date that for sidelined?
