I think jumping to the conclusion that he's lost all feeling for you isn't right. Unless he had no feelings the whole time (sounds unlikely) then I doubt he's stopped thinking about you. After I had a girlfriend cheat on me once I had to cut the relationship off and never talked to her again, but I still had pretty strong feelings afterwards that took a while to subside even though my opinions of her drastically changed in less than a day. I'm positive the breakup has been pretty much the only thing on his mind since it happens only a few days ago. Most guys like to cover up our emotions in a situation like that.
I would say the best thing to do is give him some breathing room and let him process what's going on. The hard part is that you have to resist the urge to make contact for a period of time.

Respect his choice and leave him alone. Mayhe he will miss you maybe not. Don't clinge on that hope tough and focus on your life. If you see somebody else but think about your ex it isn't fair to the third person don't you think? Be honest with him and yourself, move on, heal and then maybe you ll realize you don t even want to get back together with your ex.
