He DOES, however, now have a history of threatening violence (breaking doors down and using abusive language), so that should act in your favour.
Also, you still get to choose if he's going to be on the birth cert or not. More food for thought.
It does sound like there will be a relationship with a father, just perhaps not with the bio father.
I reckon he can earn his title, and not by harrassing you at the birth or in the lead up to it.
