Can't let you go...

How can you walk out and be fine
How can you not look back and cry
We are so perfect for each other
And you always told me that I was the perfect guy

I just want to grab you and tell you I love you
Share all these feelings deep within
Tell you how I have missed you so much
But I don't know how or where to begin

I know you won't listen because you are with him
You know you should be with me instead
But what can I do to prove it to you again
What is there left that I haven't said

I guess I haven't just flat out told you
That I am so deeply in love with you
And told you that I want us to be together forever
I guess there are many things that you don't have a clue

I've tried to let you go, oh so many times
I have tried to convince my heart to find someone new
But how can I give my heart to someone else
When it will forever belong to you...
