I Don't Understand

How am I supposed to move on like that Cause I see you with her going down your own path It's only been a month, but I'm still alone I don't think that I can do this on my own And I don't expect you to come running back But I don't get how you forgot me so fast I don't understand I don't understand Do you think of me When you hold her hand Cause I'm feeling low Without you by my side And I need to know do I cross your mind Cause I don't understand I don't understand I don't understand You told me that you'd always be mine Then you went and ruined my piece of mind Was this just a game Did you even care You moved on so quick This just isn't fair Cause I can't comprehend You told me she was just your friend Now I see you doing things we did What am I supposed to think of it I don't understand I don't understand Do you think of me When you hold her hand Cause I'm feeling low Without you by my side And I need to know do I cross your mind Cause I don't understand I don't understand I don't understand What am I supposed to do without you You were my world I never thought we'd be through Now I'm done feeling broken and bruised And I'm so tired of being used I don't understand I don't understand Do you think of me When you hold her hand Cause I'm feeling low Without you by my side And I need to know do I cross your mind Cause I don't understand I don't understand I don't understand
