Anyone else thinks this is a flawed concept?

Hear me out :

If you don't give any boundaries, you have a better chance at gauging what type or a person the girl truly is without your interference / guidance. The moment she does things that you don't like, you can just next her.

The only issue with this is that there's a chance that she might have changed "for real" because of your boundaries / direction, but the chance of her changing her behaviour through your guidance is, in my opinion, smaller than the information she gains to use against you by your given boundaries.

What I'm saying is that - if you clearly state your boundaries, she now has information to use against you. If she knows you don't like her doing x and y, she might start hiding doing exactly those things - a route that's more realistic than her changing her over-the-lifespan learnt habits "for good". Why change if you can have your cake and eat it too?

I'd rather be the guy who nexts a girl because of her actions / behaviour than the guy who is in a relationship with a girl who hides her true nature because of your verbalized boundaries.

At least the first guy isn't wasting his time on a prospect that doesn't appear to be as it is.

So my question is - what's your stance on this topic, and whether or not you think it's a flawed concept.
