Go back to my ex?

So me and my ex were dating for 11 months. We broke up right after New Years and just completely stopped talking. No one cheated or anything it was just an argument that went too far. This was the worst break up because he was my first, we met each other's parents, and we practically lived together. 
After we broke up we never spoke after that but because we go to the same school I would sometimes see him around campus. At first we would act as though we didn't even see each other and  after a few months we started simply a hi and bye and that's how it's been for a while. . 
Even though it's been over a year and I had a very brief relationship after him. I miss him so much. His birthday is coming up and I really want to go get him back. Is this a bad isea? Help!
