Funny how PUA stops common sense mechanism from working.

Say "Okay" and move on and talk to somebody on. And later on you might approach again where she sees you interacting with others and see's your a cool guy.

Abundance mindset, plenty fish in the sea. You shouldn't have to chase anybody, especially if they are walking away and your on the negative scale in terms of value at that point.

Having said that there are some things that help circumvent this. Such as always try to approach from the front versus behind makes it harder to do this.
