How Do I Say This?

How can l say this?
Where should l start?
I know what I’m about to say,
May break your heart.

You say that you've found,
The Love of your soul.
And that she completes you,
She makes you whole.

I'm sorry to say,
That she is not me.
I don't know how else,
To make you see.

I know it hurts you,
I've seen it in your eyes.
I'm speaking from my heart,
And the heart never lies.

I want you to be happy,
At any and all cost.
I know how bad it feels,
To have a heart that is lost.

You deserve someone more,
The " ONE " who's truly right.
To tell you she loves you,
Everyday and every night.

Please understand,
Why l say this to you.
Hurting you,
Isn’t something l want to do.

I’m sure your " ONE " is out there,
Searching for you to see.
But she'll pass right by you,
If you're still in love with me.

When the two of you meet,
You'll shine as bright as the sun.
I’m really sorry to say but in my heart,
I feel I’m not your  “one”
