Don't know if you recognize the new name (used to be Nick In Idaho), but I just wanted to stop in -- it has definitely been a while!
First, I just wanted to thank you so much for your early support and helping me to get the ball rolling with this whole DB thing. Don't know if it will save my M, even post-D, but it has definitely given me strength and allowed me to see I will be okay with or without my W. Again, thanks for helping me take flight!
In regard to your sitch, it seems like you're pretty much in the same place as your were several weeks ago. You're still piecing, but H continues to make choices (i.e. being in contact with PW outside the work environment) that cause backslides. Things are good, then H disrespects your established boundaries. However, it sounds like you're letting him know this more and more. Have you moved into the spare room yet, or did that idea never materialize? I personally think that this is an excellent idea, and it should really give H something tangible to help him reflect on.
Take care of yourself and stay strong in your resolve!
