My wife moved out for the second time last week. The first time, i helped her move her stuff. She didn't have anyone else to help her and I got tired of her coming and grabbing stuff at her convenience. So, I helped her pack her stuff, and move it.
This time, I am not helping her. If she wants to go she is going to have to do it by herself. I will start packing her things and putting them in the garage, but as far as helping her move it to her new place, not this time.
The ironic thing is, she got her new place last week, and she has been staying here the whole time. She is sick and needs to be taken care of. I am sure as soon as she feels better, she is out the door.
As far as your W saying she wants you to pursue her, and then when you do she puts up a wall, that sounds to me like she doesn't know what she wants. Have you noticed anything that is working. It may be small, but look for something and then improve on that.
