My start with you

When I first met you I thought that you were all I need but now I don't understand what happened between us cause I can carry all the drama without any explanation the heart breaks everytime I see it in your eyes you make me feel guilty bur I'm not, yes you are, you are, yeah yeah yeah you are, I can carry on all of this so I need to say goodbye, say goodbye, say goodbye, I'm gonna miss you, miss you.
