sorry to hear about your sitch. don't give her db to read, you will need that in your back pocket and if she knows what your doing, it won't work. as for the 180, i have read and reread that section. i have come down to the perspective that i 180 from the man that was part of sending this into a downward spiral. so for me, i was distant, withdrawn, angry, drunk everything bad prior to the bomb. work drove me nuts and home was basically a place to escape from life. so for me it is not being that man that was there prior to the bomb. now i'm open, cheerful, calm, enjoying life and things i do.
but that is not to say, if your doing one 180 and nothing is working, try a diffrent 180. think of the example with the h that always complains about his project and the w tries to offer advice. then one day she pounds her fist and starts yelling about the boss and not at her h. h is set back and has to think why is acting like this, oh its because of my prior behavior.
just keep db'ing and hand in there, if she wanted c'ing just a few weeks ago and now nothing, i don't think everything is lost.
