Selfish in 'NSYNC

I just don't understand,
Why you're running from a good man baby,
Why you wanna turn your back on love,
Why you've already given up,

See I know you've been hurt before,
But I swear I'll give you so much more,
I swear I'll never let you down,
Cause I swear it's you that I adore,

And I can't help myself babe,
Cause I think about you constantly,
And my heart gets no rest over you...

(CHORUS)
You can call me selfish,
But all I want is your love,
you can call me hopeless, baby,
Cause I'm hopelessly in love,
You can call me unperfect,
But who's perfect?
Tell me what do I gotta do,
To prove that I'm the only one for you,
So what's wrong with being selfish?

I'll be taking up your time,
Till the day I make you realize,
That for you there could be no one else,
I've just gotta have you for myself,
Baby, I would take good care of you,
No matter what it is you're going through,
I'll be there for you when you're in need,
Baby, believe in me.

Cause if love is a crime,(hey, yeah)
Then punish me,
I would die for you,
Cause I don't want to live without you,
What can I do?

(CHORUS)

Why do you keep us apart,
Why won't you give up your heart,
You know that we're meant to be together.
(doo be doo)
Why do you push me away,
All that I want is to give you love,
Forever, and ever, and ever...

(CHORUS)

Selfishly I'm in love with you,
Cause I've searched my soul,
I know that it's you. (3X)

I'll prove that I'm the only one for you,
So what's wrong with being selfish?
