I would never hit my g/f, she has never tried to hit me but if she did it probably wouldn't hurt anyway, lol.
If they did I would try to restain her or just push her back if it was too dangerous. The other thing is to let her beat you and then when she calms down she will hate herself and she will make it up to you double. If you dont even threaten her and she just hits you she will feel bad, just hope she doesn't get you too bad.
