I just can't take it anymore!

Ok so everyone who actually reads this knows how I feel about Justin. I still love him a lot but I question how much longer I will wait. I've turned down two relationships from two really nice guys because my feelings for Justin is just too strong to try and date someone else. I will give anything to be Justin's girlfriend I can't take being his friend anymore. I don't want to lose him to another girl. I don't want to lose him ever! I wish I could just come clean and tell him the truth but its not as easy as it seems to be. Nothing is ever easy as seems to be sadly. I've known Justin for quite some time now I'm so close to him yet I want to be closer. I always feel the need to be with him. I always feel like I have to talk to him but texting or IMing isn't the same I need to hear his voice whether its through the phone, in person,or over our voice chats. If I could I'd be with him every day! I really do feel like I want to marry him but I can't tell him that not when he only sees me as a friend. Why is it everytime I crush on a guy the guy only likes me as a friend and when a guy actually likes me more than a friend I don't feel the sameway? I know I've said he could be the one to a few guys already but for some reason I feel like Justin really could be the one. No one makes me feel the way he does. I can't stand not being away from him. Texting him does satisfy me sometimes but not completely. I want to go back to high school where atleast we saw eachother everyday. The place where almost every period we stood in the hallway and talked between classes and always ended up being late to class. I don't care if I always got detention for it I was happy being with him and that was all that mattered to me.
