Falling in love with my best friend

I fell in love with my best friend
She'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 she was the one for me
but now ill never know
if she 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
She means the world to me
I gave her my heart but she tore it apart
I'm the one she never sees.
