"I love you, but i cant be with you"

What am i suppose to do? Just move on, cause i clearly cant. Ive been trying, and trying. Nothing works. I tried forgetting about you, but trying to forget about you is trying to remember someone i never met. You give mix emotions, you throw words at me that mean the world to me. Everytime you say you love me, i just feel like the happiest girl alive. But when reailty hits, i know you wont be mine at the end of the night.
