Letting Go

How can I protect myself
Against an enemy I know nothing about
My seclusion has given me a false sense of security
I thought keeping to myself would protect me from you
I thought I was untouchable
But my lonliness only made me weaker
It made my desire to open up to much to control
I bottled my emotion too long
Till I finally couldn't hold any more
I attached myself to the nearest person
That person touched my heart unlike any other
Unfortunately that person was you
Now I'm not sure what to do
I know I can't have you though
We both belong to another
I've been trying for so long
Just to let go of you
To free my heart of your memory
It has never worked though
I can't seem to take you out of my heart
I tried to replace you
But the thought of you ...
It overpowers my love for anyone else
What is it going to take to get you out of my heart
To what length or extreme must I go
Will I have to remove you from my life completely
I know everything about us is meaningless to you
So why do I still hold on to my hopes
You are not going to change your mind
Besides, you are so happy now
I don't want to make things complicated
I just need to do this on my own
But I need you to help me let you go
Why did it have to be you
