Aww. Im sorry.
It's good that you realize it's not the end of the world. When I broke up with a boyfriend a few years ago, I felt like it was.. you're lucky to be strong enough to realize that. =D
If the reason for your break up was petty, then maybe he feels the same. Talk to him about it, and if you really want him back--then just tell him. Make sure that's what you want though, because it wouldn't be fair to him to get back together just to break up again in the near future, especially for the same reason.
I hope you feel better
