Where is your love?

Your heart is not with me,
For it has wandered far.
We were not meant to be,
But your happy the way you are.
I'm not gonna get upset,
I won't let you get me down.
Because of the girl you met,
I won't let you see me frown.
My heart will mend in time,
It is like a jigsaw.
Yours was never really mine,
But you have left this one raw.
Please get over her fast,
Don't let this one last.
