I Have Been Feeling Very Down Lately

My boyfriend of 6 almost 7 years now is moving next August to another city for school while I am still here then transferring to a different school in another town. I asked him what are we going to do about us and he said he hasn't even thought about it. I understand getting everything ready and dealing with this is all time consuming and everything but it kinda hurt knowing that us is just an afterthought. I have always felt that I had more feelings in this relationship then he had but I just thought that it was just a "guy" thing. I think that when he leaves we are going to have to break up and he is such an amazing guy and works so hard and doesn't let anything stop him. I know I am only holding him back but I don't want to not be together. I love him and he is my first everything and I can't have that with anyone else. I have been trying really hard not to let it get to me that we only have summer left and then he is gone. I try not to show that is hurts me every time he gets excited about leaving and telling me all he has left to do because I want to be there for him and be a part of this with him. I know that when I think of it I get a little teary and I don't know id I am just being over dramatic about all of this or a little selfish but it is how I feel about this whole situation. I want to be angry with him for being so smart and always moving forward lol but I can't. I am so proud of him and everything that he does. I don't even think that I can be friends with him when all of this is said and done because there are just too many memories that I have and I will always just want something more. I know I cant tell him any of this because I don't know if it'll make him feel bad or angry. I want him to be happy and excited. Even going into this relationship I knew he was always going to be moving forward and away from me because of the person he is , I think that I just kinda hoped that things would be a little different or it wouldn't have been so bad and painful. There is so much more I can say but this post is already getting a little long and I am starting to get into my feelings a bit -.-
