I'm the centre of your world I will let that core grow cold I'm the blood within your veins And I let your heart grow old I'm the tears within your eyes When you try to fake a smile I am the words you tried to hide In every desperate dial I'm that emptiness beside you When you're not together I am the lies that she told you When she promised you forever I'm the thoughts within your head When she'd ask "Are you alright?" I'm the words you both spoke Just to avoid a fight I'm the seconds that drag on When you're staring at the phone I'm your final plea "Don't leave me all alone!" I'm that sock that she'll forget That you'll find months six later I'm the denial that you face When you pretend that you hate her I'm the balcony you stand on When you want to jump I'm the ground below you I meet you with a thump I'm that aching feeling When you last saw her face But you know you love me I can't be replaced
