Will seeing an ultrasound move him?

He's been a complete jerk since I told him I'm pregnant. I'm 10 weeks now and have an appointment with an ultrasound scheduled for tomorrow. He said he'd come. We'll see. But will seeing our baby on the ultrasound and hearing its heartbeat possibly move his feelings and push him to not be a jerk? Or will he possibly act worse? He hasn't wanted to assume responsibility. He's been giving me a hard time stressing me out and some other things.
