Why can't you see, I want it to be me?

When I see you,
My heart skips a beat.
When your near me,
I only hear your voice.
When you tell me,
You love me,
I want to be with you forever.
But when you are with him,
Everything falls apart.
When I see you hug him,
I wish it was me.
When I see you kiss him,
Oh how I wish you knew,
That I want it to be me.
When you hold his hand,
All I feel is yours in mine.
Cant you see?
I want it to be me?
I want to more than your bestfriend.
I want to be there for you,
When you are angry.
I want to hold you,
When you are upset.
I want just want to be with you,
Every second of the day.
Every second of the night.
When you message me
And tell me,
How much you love him.
My heart breaks in two.
Jealousy takes over,
And I tell you,
That I love you to.
Thats when it starts,
You realize what I am feeling,
That I just love you too much.
And every time I see you with him,
It digs my grave even deeper.
But now you realize, and finally see.
Whats makes you happy,
Is hurting for me.
I want you to be happy,
But being with him makes me sad,
So this can never work out.
I must go,
So I will say goodbye.
I love you more than anything,
Just know that I do.
I'm sorry about what I am going to do.
I know it will hurt you,
Something I swore to never do.
But if this is what it takes,
To rid me of this pain.
Then this is what I must do.
Goodbye.
You are all that I care.
I love you.
