How to get him back?

Okay so I've been going out with this boy for 9 months, and before that we were best friends. Our relationship has been overall happy, but we're both really stubborn and fought a lot.. 3 days ago he broke up with me, and of course I'm devastated. This is most likely because we got into a fight the day before at his house and I threatened to leave and started sobbing. He begged me not to leave and held me, but I had to leave before we could fix it. I Ignored him the next day. He called me to break up, and then after he hung up I called him back once again to ask him if he was sure and he said he was. He said he was tired of all the fighting and that making up just didn't seem worth it anymore. Then 5 minutes later I called him to tell him I didn't know who to talk to about this, and he suggested our mutual friend and I hung up. He said he wanted a clean as a break as possible. I didn't cry or plead, my voice was calm. Then 2 days ago I left him a voicemail asking him just to be friends and start over, because we were both each other's best friend. This sounded cheerful and sincere.

He texted me "Hey, can't decide what I want to do now, I think we should wait until finals and school are over and we can reevaluate then, but there's just too much right now." That's 2 Monday's from now. Do you think the no contact rule is a good idea until then, and that I should let him contact me first? What if he never contacts me?
