While I don't know anything about arias, I do think Andrew Lloyd Webber's I Don't Know How to Love Him from Jesus Christ Superstar fits the playbill perfectly.
I don't know how to quit him.Ha, this is easy. I should be in musical theatre!
What to do, how to split from him.
I've been changed, yes really changed.
In these past few days, when I've seen myself,
I seem like someone else.
I don't know how to take this.
I don't see why he moves me.
He's a man. He's just a man.
And I've never had a man before
In any way,
He's just one score.
