My husband just hit me. A slap across the face. Im at a loss what to do. We were quarreling and it just happened. He immediately apologised and said it wont happen again.

Woah ... what are you entertaining & why are you entertaining. A slap? That's violence woman.. Stop it now.. 'Wont happen again' is just a temporary assurance till it does. Remember-what you allow is what will continue.He has shown you clear signs of male battering..Firmly tell him to back off such behavior... Be strong-understand what you can do to stop such behavior.. Consult someone legally for extreme case. Also do you have kids who have witnessed this? Even more dangerous...
