Whole Heart, Broken Love

I promised myself I would never have a broken heart.
I told myself that I could decide from the start.
I said I would never cry over someone.
If it didn't work out, they just weren't the right one.
I never got angry if my crush was one sided.
The pain would not touch me, I had decided.
Now my crush is crushing back.
Though somehow it feels like more than that.
He talks as if we have a future together.
But some people say we are in for bad weather.
I am afraid of what will come to pass.
I'm terrified our hearts might be shattered like glass.
Can I truly love if my heart is not exposed?
Without the answer my mind might explode.
