Somewhere between

I love you so much I can't let you go and sometimes I believe you love me
But somewhere between your heart and mine there's a door without any key
Somewhere between your heart and mine there's a window that I can't see through
There's a wall so high it reaches the sky somewhere between me and you

Somewhere between your heart and mine there's a love I can't understand
It's there for a while then it fades like a smile and I'm left in the middle again
Somewhere between...
