Girls are like dogs, their 'focus' is on whatever shiny toy is in front of them at the moment. For a moment, you were that shiny toy. There are now other shiny toys getting her attention so that fleeting emotional state that compelled her to respond in the first place is gone. Their view on reality is very different than yours, they aren't mentally capable of maintaining a logical hold on their emotions the way you are. There is no object 'reason' to them.
It's best to fuck them as soon as possible, the longer it takes the more likely her fleeting emotions move on to the next dopamine spike in front of her.
