Re: got a number THEN TOLD TO ERASE IT!
I triple that response. If you do want a chance with that particular girl, she is going to have to see you hanging out with other girls to trigger the preselection switch in her brain. Also, if you show that you don't care that she told you to delete her number it will be a huge dhv. It will show that she doesn't impress you that much and that you value yourself higher than that.
I would suggest still being her friend and acting like it never happened. That way it will really get under her skin. In a good way. She has to see it doesn't bug you. Don't make it obvious and chase her around or something. Just if you are both in a mutual conversation or something treat her normally.
There is no such thing as rejection, only feedback.
Be the flame, not the moth.
