Let you in

If I could,
I would let you in.
But as I am now,
You need to stay out.
I need to change,
From the inside out.
All you ever wanted was...
Me.
Four months ago,
I hadnt expected much.
But now I know,
That your different.
You care.
You once were my prince,
And I your damsel.
You saved me,
and I had saved you.
But now its my turn to save myself.
