Agree totally with JTH (for once!) - go to the police, this was rape
While she is in with a solicitor getting the injunction orders to prevent this again/kick him out of the house, file for divorce as well. It is likely that the solicitor would look to minimising what the pay out from the house is, as there is also no kids involved. Tale advice, it's crucial and there's no need to give money away, particularly when he has been abusive/violent.
Agree with JTH on the property too
