Orich, Been catching up on your thread and others. I was immediately going to suggest reading steady's "What I've learned about detaching", and then I saw he already brought it this thread.
So, now my advice is reread it, reread, reread it.
I printed it Friday before going away and must've read it 20-30 times times so far.
It is excellent.
You can do it. Thanks, steady!
And I think her speaking brusquely and sleeping on the couch proves your Dbing is getting to her comfort zone. And if I'm wrong, speaking brusquely and sleeping on the couch should be interpreted as nothing more than speaking brusquely and sleeping on the couch. It won't last forever and will probably not last long at all if you do not acknowledge it. Ignore it.
