So close but still invisible

What do I have to do to get you to notice me?
Change my hair, the way I walk?
My clothes, the way I talk?
We've known each other for some time now,
Yet I'm still invisible to you.
My feelings run deep and how
I wish you only knew.
I see your face every time I close my eyes.
To me, you just seem so different from the other ladies.
To you, I'm just a friend,
Nothing more, nothing less.
I settle for friendship in the end
Because I don't want to make a mess.
Instead, I'll keep my secret to myself
And take my pride back off the shelf.
Until one day you finally see
That you and I were meant to be.
I'll wait for now but not too long
Because sooner or later I'll be gone.
So when will you notice me?
