NC isn't a game. It's basically about giving both parties time and space to heal and figure out what they really want. One positive potential side effect is that the dumpee may miss you once they fear/ realize you're really gone, and may come back. They'll generally respect you more if you don't linger around begging and pleading or whatever. But the main thing is that if you have it in your mind that you CAN'T contact them, it makes the pain a little easier to take; you don't have to worry and obsess about what to say, how to come accross, etc., and you can concentrate on getting YOURSELF back together. I'd suggest planning on having no contact for about three months at this point. That should be enough time (it may take more) for you to regain the composure you've lost, to gain some perspective, to see if you still want him, and for him to miss you.
