One more thing. You need to tell your W that you have packed your bag and will not be coming home until XYZ condition(s) is/are met. She needs to know what is going on, otherwise there is the possibility that she is surprised by your not coming home and has no clue as to why you aren't (may sound surprising, but it seems to be common that the spouse has no clue how much you are hurting). You owe her at least an explanation and the ground rules for you returning. You also need to make a firm resolve for your self as to what your game plan is, including a plan for handling all of her possible reactions.
