This is a good idea, and one that I am struggling with myself (which, because I don't want to deal with it is probably the best indicator that it should be done, lol. I just hate to allow her into my precious psych time. Logically, I know it isn't about her, that's just my reaction.). I'm in a somewhat similar work situation where there is very intentional nastiness toward me with ridiculous fabrications thrown in. In fact, I left early today to not cross paths with this person because I was very upset already and knew it would send me over the edge. My personal experience is that, even having expressed my frustration to the owner (over only the very worst incidents), the person has ingratiated themselves to such a degree that it is a total no-win situation. So….I have to agree with the others. Walk away. I'm too stupidly stubborn to take this advice myself, and can assure you that fighting a hopeless situation won't do you any psychological favors.

They don't even know about the BP, btw, but , doing a whole lot of "can't prove it" stuff still manage to make me look crazy if I speak up. Yeah. Run.
