Unsure

I am unsure.
What are we to each other?
I love you, you love me,
I hurt you, you hurt me.
Endless circles,
Arguments day and night,
Passionate embracing,
Scorn-filled words.
What am I to you?
Friend, lover, fiancée,
Future mother of your children?
We love, we fight
And I am unsure
Of where we will go.
Do we stay together
Or will the pains we carry
Tear us apart?
Uncertainty fills my mind,
I am unsure.
