Falling in love with your friend

I fell in love with my best friend
He's always on my mind
I fell so hard I squint my knees
And now ill always have these scars
Through life I'll always wonder
if he was the one for me
but now ill never know
if he was the who held the key
our background is a little hazy
all I know is we've always been friends
I wish there was more to say
But its ended now, its crazy
I fell in love with a friend of mine
He means the world to me
I gave him my heart but he tore it apart
I'm the one he never sees.
