"For Her"

With you, I know I can do anything
The up-most purpose is what you give me
The way my heart feels, it wanting to sing
Being next to you is where I should be
The feeling I have is something you don't
That smile on your face is not caused by me
This way I feel, the way you don't, you won't
It's ok, be as happy as you please
I will remain here watching you love her
Your love for her, I see it in your eyes
But I just have to ask you, Are you sure?"
You not choosing me could cause my demise
If in fact your love with her does not last
Keep in mind that you left me in your past
