"Has not [the LORD] made them one? In flesh and spirit they are his. And why one? Because he was seeking godly offspring. So guard yourself in your spirit, and do not break faith with the wife of your youth. "I hate divorce," says the LORD God of Israel, "and I hate a man's covering himself with violence as well as with his garment," says the LORD Almighty. So guard yourself in your spirit, and do not break faith."  (NIV)

     To my mind, this is crystal clear.  God does not want His people to get divorced, though if you are currently in a physically abusive situation, get out of the house and seek help at your local women's shelter!  God's Word makes no provision for a husband to physically injure his wife under any circumstance.
