Exactly, by removing yourself from the situation, taking the kids away from time to time will allow her some space and time to herself tosee that things that are upsetting are not your fault. Do not let what she thinks about you change your plan. Trust me on this. It kills me when I think about her and how can I win her back, when there is nothing I can do. I get great support over at my posting and trust me, you will soon be where I am. Deal with things you have absolute control over, disregard the rest. If your kids bring you joy, spend quality time with themaway from her. You are not getting them to play favorites, you are showing them you. She will be watching and wondering why the change. If she asks, tell her its just somthing you felt like doing. Do not dwell on answers to her questions. If she doesn't start a conversation, then you shouldn't have one with her. It is hard to do being under one roof, but consider it.
