Lyric:
I Don't Wanna (Have to be the One to Say Good-bye)

I don't wanna share tomorrow
I don't wanna bear another sorrow
I don't wanna say "It's over..", but I can't lie;
(It's over baby..)

Maybe we should find a reason
Maybe you could say that I'm not pleasin';
But leavin's in the air, and leavin' makes me cry;
And I don't wanna have to be the one to say Good-bye.

Yesterday our love was speeding;
Didn't think it would be needing feeding
So we stood and watched it fade before our eyes
(It's over baby..)

Guess we better talk about it;
Guess we're gonna have to live without it;
We've become a tangled knot that won't untie;
And I don't wanna have to be the one to say Good-bye

Do we have to keep pretending?
Mustn't be afraid of ending it?
Isn't any hope of mending it;
So let's stop here,
Without a tear.

I don't wanna pick up pieces
I don't wanna sign no long-term leases
Time to let it go, we've passed the time to try;
(It's over baby..)

Tell me that you understand me,
Tell me can fall apart and land free;
Tell me what you want, just look me in the eye;
Cause I don't wanna have to be the one to say Good-bye
I don't wanna have to be the one to say Good-bye
I don't wanna have to be the one to say Good-bye

(Break)
Do we have to keep defending it;
So let's stop here,
I can't take tears.

I don't wanna start explaining
Nevermind the smiles, inside it's raining;
I see it in your eyes, your heart, your hands, your sighs;
(It's raining, baby..)

You've been there before to cheer me;
Long ago you swore to hold and hear me;
Now everything is done, just help me one last time;
Cause I don't wanna have to be the one to say Good-bye
I don't wanna have to be the one to say Good-bye
I don't wanna have to be the one to say Good-bye
