I hurt my ex alot. i miss him like crazy! it tears me apar, will i ever get him back?

we met last summer. he was the first person i liked alot and opened to. he is two years older me. im 20. we live in different cities, far away and i would delete him off my msn because of small arguments. i was depressed, and would depend on him to be happy since i was never in a relationship. he even told me not to delete him, but i was immature, and idk i guess its all my fault. he eventtually blocked me from facebook and msn because of my immaturity which was in december. i miss him so much, i always think about him. im in my second year of university. im planning to move out to his city. and yes i can get other guys, i am pretty, and fit. all i want is him though. it tears me apart thinking of him with being with someone else. advice please?
