Somewhere Between lyrics

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
[ Lyrics from: http://www.lyricsmode.com/lyrics/b/bonnie_owens/somewhere_between.html ]
I love you so much I can't let you go 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 love I can't understand
It's there for a while and it fades like a smile and I'm left in the middle again
Somewhere between...
