I would let the hospital staff know about this and have him banned from further attempts to contact you.

If your parents can't honor and respect the damage this bastard has done to you and forbid him from attempting any contact with you, then perhaps the hospital needs to ban them too!

This totally sucks and it also sabotages your healing process!

Feel free to show this to your parents and tell them I said to do the right thing for you or go pound sand!
