I was lonely, only I didn't know it   I was so sad, only I didn't show it   You came like the sun breaking through the clouds   And I found you're what I couldn't live without      In you I feel the other half of my heartbeat   I'm complete   In you I hear the other half of my heartbeat   That's all I need      You know I didn't know what I was missin'   Oh, but baby since we've been kissin'   Oh, I can feel the other half from the heartbeat   It's so sweet lying here with you      You'll look at me and I see my reflection   You understand who I am needs protection   The way you latch to me, the way you take my hand   And I follow you to fall in myself      In you I feel the other half of my heartbeat   I'm complete   In you I hear the other half of my heartbeat   That's all I need      You know I didn't know what I was missin'   Oh, but baby since we've been kissin'   Oh, I can feel the other half from the heartbeat   It's so sweet lying here with you      My heart beats like a drum when I hear you come      You came like the sun breaking through the clouds   And I found you're what I couldn't live without      In you I feel the other half of my heartbeat   I'm complete   In you I hear the other half of my heartbeat   That's all I need      You know I didn't know what I was missin'   Oh, but baby since we've been kissin'   Oh, I can feel the other half from the heartbeat   It's so sweet lying here with you
