A piece of mine

If you’re not the one then why does my soul feel glad today?
If you’re not the one then why does my hand fit yours this way?
If you are not mine then why does your heart return my call
If you are not mine would I have the strength to stand at all

I'll never know what the future brings
But I know you're here with me now
We’ll make it through
And I hope you are the one I share my life with
