Jealous of Only One Thing

There's only one part of me
That honestly is envious
It is only of those friends who
Will always take my place
Of your happiness?
That's a bit doubtful
But of her?
Oh, yes, of course
Why not just say it?
Say that I'm not enough
Say that I'll never be close
Say that I'm not worth your time
Say that I'm just a pity friend

Say it
Say it
Say it

Prove to me that you care
'Cuz I honestly doubt it now
I'll never be her
I'm never going to be

Jealous of him?
That'd be ridiculous
Just a friend
Never more
I want you happy
But I bet you doubt that
Too, don't you?
