Another issue for the OP to consider is that the longer you stay the more likely things are to spiral down the drain. Are you willing to risk her flipping out sometime and calling the COPs on you claiming you hit her or something other lie just cuz she is mad at you?
The true alpha thing to do at this point is put your guard up and start thinking defensively. As long as you're still under the same roof.....you're on dangerous ground.
