Hi 25, I'm still not there with my DB coach, hopefully soon... As far as the NC letter, I found one and used a variation of it. My W took it to her psychiatrist (her second visit) and he said that they she should be trying to undo why she has secrets and lies and it is not truly coming from her, so she shouldn't send it unless it from her words. Needless to say, it's not sent. He also advised that I should come in for a session. W claims that her heavy lifting is working on her own problems first, thats frustrates me. She has to undo herself to get back on track is her claim.
I'm finding it hard to detach because we live/work together, but I am GALing as much as possible. I bought and read the DR book and found it helpful.
