What I mean is she is questioning whether or not we can make this work and she is being a bit cold. I try to act as if and it is quite difficult in this sitch but I think I am doing ok with it.
Remember, my H did the same thing. He said 2x he was ready to move in or thinking about it. He kept wavering too. So did I. Think about what W needs to trust that it will work and begin trying those things. For example, H needed to see that I could relax a bit if things got stressed and not blow a gasket. I had to continue to remain calm under pressure and not blow so he could see the changes in me.
What does W need to see? Is it time with the kids? Is it doing yard work? Paying the bills on time? Taking her to the movies? Cleaning the house? Cooking dinner?....
