I'm sorry if I'm wrong

Do you remember when you said: "This feeling needs to stay forever"? Well, I thought it was true but now, I see it wasn't. You have to know I'm so sad about this. I like you. I want you. I need you. Believe me when I say. Maybe you'd better follow your life, but I just ask to you never forget me 'cause I'll never forget you and I don't need to promise, I know this.
