Great and important post coming from experience.I couldn't have said it better.
To add my own spin, this is why I'm always preaching to hold them accountable and judge their behavior, and call them out on it. Forget about this "Don't appear butt hurt" nonsense. That attitude is the attitude that perpetuates their bratty, entitled and sneaky behavior.
Call them out! When you do, you're not displaying that you are weak and hurt. Rather, you are conveying that you have standards and you have absolutely no qualms about standing by your standards and rejecting women for not meeting them.
I wish this community would let go of this "Don't let her know she got to you" attitude. This is the very oil in the machine that continues to churn out women's outrageous and immoral behavior. You don't need to appear hurt. You need to calmly and in a detached way let her know that you will not have this in your life, so "Sayonara".
Be a man of standards and rules, and watch how women start to respect you and watch how they don't dare to pull this kind of crap.
