I agree with sandi. You said that she wanted to work on the M. This should include no contact with OM. There is not trust there with him in the picture.
I will tell you that if you confront her about the OM, she will turn it around and make you sound like the unreasonable one for denying her a friendship, etc. Just remember that's all part of her craziness like someone on drugs.
Stand strong.
