Look, stop seeing this as breaking up your family. All I was saying was to get away from her for a few days. Why is that so difficult for you? I understand the part about post surgery care, but apart from that.......you are using "breaking up the family for temporary reasons" as your excuse?
Why couldn't you see, "I need to get away a few days in order to save my family"? What about her seeing what she was losing? But instead, you hung around to get kicked in the teeth.......again. Even when you are doubting your own feelings for her? You had rather stay till neither of you can stand the sight of each other?
Well, there is only a window of time where walking away is effective in the WW's attitude adjustment, but that's just me.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
