Choices

Why is this so hard?
Why can't you see?
You should leave her,
You'll be happier with me.

She isn't as good as me,
She'll never take my place.
When you look at her,
Do you see my face?

I know so much about you,
For we are best friends.
And for you,
I will fight til the end.

You need to make up your mind,
You need to choose.
Cause if you don't,
Then we are all going to lose.
