110% with Nomo on this one, Heim -- PLEASE DON'T DO IT. Only if you are done with trying should you do it, because the bottom line is that you will only show her pressure, control, etc, that will in turn frustrate her and either push her away further or cause her to put the final nail in the coffin. Is that what you want?
She KNOWS you don't want her talking to OM, so why keep bringing it up? Please don't do it Heim.
