Excellent points!
Problem is, unless you are truly in touch with yourself you might never make that assessment.
To be truly in touch with the real you requires a degree of honesty most can't possess.
For those that do, its a simple thing really.

Problem is, there are far too many people that are deluded about what it is they want and who they really are.
See, the thing about delusions is they are extremely convincing.
It takes serious discipline to remove delusions and actually know the true self.

In this instant gratification, self-empowered society it gets muddled fast and stays muddled.
It requires an honesty most can't understand till its forced upon them.
We usually tend to "give in" to the easier path.

I don't see the OP as a deluded person prone to reactionary decisions.
I see her as an intelligent woman with a great sense of self.
The topic solidifies this because she is pointing out something that most people just dismiss.
But, her view is kinda one sided.
I have noticed much the same thing concerning women on dating sites which leads me to the understanding that it is not a gender specific issue.
Frankly, I subscribe to pretty much the same opinion in my own encounters.

Its like people act according to stereotypical behavior instead of natural behavior and it gets really old, really fast.
I understand that there is nothing I can do about it except dismiss them and move on. As far as I'm concerned, that's enough for me.

See, there are a few thousand potential matches on any given dating site.
Some of those potential matches are ruled out immediately and others need some effort. Thing is, I only really need one match. Everyone else is a non-match and can be dismissed.
So, when some woman plays it wrong, its one less woman I have to expend my time and effort on to find out if she truly is...the one.
