You're here...Are you?

You're touching me. And then you're kissing her.
You're acting like I'm your best friend. And then I don't exist.
You're here. And then you're not.
You're important to me. But you're leaving.
You're here now. Why can't I enjoy that?
You're everything that I dreamed about. Why aren't you perfect for me?
You're playing with my hair and you told me I'm beatiful.
You're playing your guitar. And you said you want me to be around.
You're talking on the phone. And looking at me in the same time.
You're talking with everyone about a movie you saw. But your eyes are mine.
You're playing ping pong. And when you win a point. I win a smile.
You're putting your hand in my shaking legs. I'm tense. You're worried.
You're asking me what's wrong. And you got mad when I said nothing.
Youre making me jelously because your pizza came first.
You're making me blush. And then you're with her.
You're stealing my heart. And then hers.
You're daring me to do somethings. Which would please you.
You're here. And then you're not.
You're...Where are you?
