Your husband can ask his solicitors to apply to the court for his bail conditions to be lifted. However, it is extremely unlikely that even with your support they will be. I imagine one of the reasons for the conditions is that a) interferance with witness (ie discussing the case with you) and 2) to prevent further offences.
The Domestic Violence protocols that the CPS adhere to means that once they have a statement from a complainant detailing domestic violence, they WILL pursue it - irrespective of your views. Unless you can present the court with some extremely persuasive evidence of your difficulties without him, I think it extremely unlikely his conditions will be lifted.
He might want to take legal advice with a view to entering an early plea (or at least coming to a deal with the prosecution) and that way make it go away a lot quicker. Although if he pleads on the facts you have given, he is likely to be facing a custodial.
