lapoo, my sitch is a little different, but I found setting boundaries for the OM made a huge difference for my ability to respect myself and also make my intentions going forward clear. It was not easy, there were some unique issues that occurred, but overall it made a huge difference as it let me focus on me instead of what was being "done to me" as I saw it at the time. I thin you need to explore how to set some for you.
