"people always leave.." :( :( please answer anyone?

became friends with this guy blake back in december. We became really good friends and pretty close. We eventually began to like eachother alot as more than friends. We had alot of amazing times together and the way he viewed things and just life in general had such a big impact on me. We went to prom together which was probably the best night of my life and after that we became really close with eachother. But he had had plans to leave and go up to school for 3 months and he already left about 2 weeks ago and i miss him so much. I didnt know it was gonna be this hard and i didnt realize how much he meant to me until he was gone..the night before he left he bought me dinner and cuddled with me and held my hand and kissed me. And then he left the next day. its only been 2 weeks but it feels so much longer and he doesnt come back home until august. I have no way of talking to him because he doesnt have a cell phone. So i have no idea how hes doing and i dont know what to think..I dont know if i should wait for him or just move on cause this hurts so much to just stay here without knowing what to do. Im afraid he's forgotten about me or he just doesn't care. I miss him so much and nothing is the same without him around. My best friend told me today that he's liked me ever since the start when me and him met but he was too afraid of getting hurt to say anything and he didnt want to start anything since he knew he was leaving but me and him just got close with eachother anyway..:( and she said that he always looked at me in a special way and i had always had people tell me that blake thought i was so beautiful but i didnt think there was anymore to it. what should i do? I just found out today that me and my friends are going up to see him on june 15th and im excited but nervous....://// i just wish i knew if he was thinking about me too..Im having a really hard time with him gone. I dont even know what im waiting for anymore. We are both 16.
