I haven't even read your thread but I can share a bit about me. I've figured out that I lose 5 lbs and a week's worth of forward progress every time I dig into W's facebook activity. When I'm in that mode it is destructive for me and I can almost see her running the other way.
Don't look. It is empowering. Just don't!
