Who am I without you?

 I know you loved me. I know, all you want is me to be happy. I know, I was everything to you.
It was my fault. Leaving you without saying good bye. You gave me all you had, and I let it go. Just like that.
I thought I could live without you. I thought I can breath without you. I thought I can open my eyes realizing that you're not there.
But I was damn wrong. Seeing you with other girl broke my heart yet makes me happy cz now I can see you smiling from your heart. I know that girl deserves you better than me. She makes you smile, happy like this world is yours.
Now, I know how hard it is to live without you. It aint easy for me to breath now cz you were my air but I didnt know that. Its hard for me to wake up and open my eyes realizing that you are not there anymore. You are not in my world. And I just realized how much I need you now.
You gave me your love and what I gave you was only goodbye.  I need you now, right here.
