Why don't the tears stay

There's nothing I can do,
My heart is black,
And it's only from you,
I want to go back,
And ask you out before he did,
And maybe then,
I wouldn't feel this,
You have the choice of men,
So why should I feel defeated,
Oh I know why,
It's because i'm the "sweetest",
Girls don't want a sweet guy,
Now my tears are gone,
And I feel dejected,
But perhaps i'll take a chance on,
My love not being deflected,
So my dear sweet,
You are my anti-theca,
Getting you will be a great feat,
Getting you...Rebecca...
