One day, I promise

I'll make a promise to you,
One day we'll look at this and laugh,
One day, we'll make jokes 'bout my heart,
and how you stole the other half.

One day I promise
that we can hang out,
And sit next to each other,
with no feelings about.

And maybe I could even promise,
to help pick out a ring for your wife,
although right now,
that would have made me plunge the knife,

One day, I'm sure there'll be,
a time when I'll wanna kiss you,
But then, I need you to tell me,
That we were over and already through.

One day, I promise,
that you can help me find a mate,
but for now, can I just cry,
cause our love was taken by fate?
