Suggest that someone is in love?

I don't know who you are waiting for, just as I don't know why you are here. I think I can't like others, because my heart is full of you. You are mine, and no one can take you away, including myself! If you don't want me, I'll find someone else, and no one will try to rob me! If you can't give her happiness, let her go and let her find her own happiness. Your name is the shortest love letter I have ever seen, but it is the best love poem I have ever used. Your name is the shortest love story I have ever heard, but it took me all my life to answer it. If my eyes can't see you, I will listen with my ears. I think I really love you, but why can't you look back at me? I think I can't like others, because my heart is full of you. You are mine, and no one can take you away, including myself! If you don't want me, I'll find someone else, and no one will try to rob me! I don't know who you are waiting for, just as I don't know why you are here. I think I can't like others, because my heart is full of you. I don't want to like you anymore, but I can't forget you, you know?
