Am i wasting my time?

I don't know what to do. I don't understand something. Are you going to go after another girl? Are you going to date someone else? or are you going to come back to me when you're ready for a relationship in your life. If I wait for you. If i wait for you to be ready, will that day ever come? or do you just not want me at all. I can't tell. It bothers me. I want to end up with you. I can't see me with anyone else but you. You're not like the rest. I need to get over you, but i'm scared to be on my own. It was so good with you, i felt happy. I was the happiest i ever was. Because of you i didn't take drugs or smoke or cut or anything. I wanted to keep you happy. I wanted to make myself perfect for you. I don't want to do that for anyone else. I want you to be in my life. That's all i want right now, is for us to be together. I want to grow old with you and experience life with you. I cant tell if you're spending your single life flirting with girls. I can't tell if you're going to get into a relationship with someone else. I wish i could ask you that. I asked too many questions. My friend told me today that you still want me, just not now. I'm not sure if he was right or not, but it gave me hope. But i see us changing. Not talking as much, and it scares the hell out of me. I think about not having you, and being alone and i just want to... i don't know what i want to do. I feel empty when i think about that stuff. Other people flirt with me and all i can think about is you. I don't want us to be over. But i don't know if I'm wasting my time waiting for you. Do you want me to move on for good, or should i wait? Are you ever going to want me again, or are you going to have someone else? Are we meant to be? Or are you just a chapter in my life that has seas to exist. I just need answers. I don't want to fall back into the position i was in last year. I don't want to go back to that. I'm tired of being depressed and sad. I've had enough of that for the past 9 years. Ever since my mother died i thought i'd never feel whole. That i'd never be able to feel happy like i was for the first 7 years of my life. When i was with him, I finally felt like there was hope. I felt happy. He filled the whole left in my heart for those years. But now that its gone, i'm empty again. I've gone through life feeling alone, and now that i know what its like to feel like you have someone i don't want to go back to the old ways. You left now, and i'm alone again. Happy didn't last long. I don't want to be sad again. Friends can help a lot but not as much as someone who actually loves you and wants you to be there's. I'm young i know. But i cant take it. I want you in my life. No one else. Just you. You don't feel the same though. How am i supposed to move on. I hate it.  Now, there's no meaning anymore. Does love mean nothing anymore?
