Wow.
I would have taken some action by now.
I commend your restraint, but am apalled at your unresponsiveness.
First off, I would have picked up my girl and taken her to the hospital regardless of what she may have to say about it. Secondly I would call the authorities and inform them of the situation and meet them at the guys house so he can see my face, OR, I would wait for him to leave the house early in the morning, cut him off, smash out his driver's window and proceed to smash his face with a bat.
