It's already happened, so try the best result possible. If you are still in H1 visa, don't take chance, hire a lawyer to handle it for best of you both. Money can be made later, not bet on anything now.
Most importantly, many couples lose their feelings toward each other starting from this kind of incident. I am not saying you and your du*****and are the same, but just want to take precautions... If I were you, I'd go back, staring at his eyes and say sincerely "I am sorry, I din't mean to hurt you...".
Wish you the best!!
