My Girlfriend Has A Boyfriend

How can I have known
Happiness so grand
It'd cause the world to stand
How can I have known
Sadness that tears so low
You'd wish that you were dead

I don't know if I feel the same
The same as I did yesterday, uh huh
Just who an I trying to kid?
I still feel the same, I still love you anyway

If you please, don't damage me
I don't think that I would last
If you please, remember me
Anytime he makes you sad

My girlfriend has a boyfriend
Can you even start to picture that?
My girlfriend has a boyfriend
I don't think that I can handle that
