'N Sync - Selfish Lyrics

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 (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 

What's wrong with being selfish??

I'll be taking up your time 
Until the day I make you realize 
That for your there could be no one else 
Ive 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 
Then punish me, I would die for you 
Cause I don't want to live without you 
Oh 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
Why do you push me away 
All that I want is to give you love 
Forever and ever and ever and ever 

(CHORUS)

Selfishly I'm in love with you 
Cause I've searched my soul and know that it's you (2x) 

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