If you have not read the whole book, now is the time to read "Putting it all together" READ IT NOW. Don't get discouraged. There is one story of a couple that took six months before they really even talked. DON'T give up.
The best thing that you can do right now is pull yourself up and brush off the hurt and WORK ON YOU! Go to the gym and work out, go for a walk in the park, call a girlfriend and go to the mall, STOP THINKING ABOUT IT ALL THE TIME. Set aside a time of the day that you will let yourself think about it and limit it to then. You have to come up with a way to let go when that time is over though. You might have it planned that you will think about it and then go swimming, or some other activity that will help you not dwell on it. And when you do think about it try really hard to see if there are any baby steps that you can see him taking. Maybe you could view him wanting to be your friend a baby step. This opens the door for more comunication.
Don't let him see you be desperate. Don't let him know how much this is killing you inside. Occationally if he asks you to do something and you have something else planned keep your original plan and tell him that you are sorry but you have something else going. THIS IS REALLY HARD. I know that you want to spend all of your time with him and figure this thing out quickly, but it just doesn't happen that way most of the time. Stay cool. KEEP TRYING.
