Stuck, I never answered your questions about the OM. It is best not to bring him up in conversations if at all possible. However, if you have a small tape recorder or some way of recording a phone conversation, then if he ever pulls that stunt again, be ready with the evidence to show her.......and maybe the police. In what way did he threaten? Is he still trying to see her?
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
