DB coach said it is ok to confront her and ask her to leave MBR, but not to pressure her about making up her mind on relationship. Having her leave the MBR is establishing a boundary for my self respect. But telling her "You need to decide if you want to be in a relationship with me or not. If you don't want to be in a relationship with me then you should leave" would not be the right thing. She has already told me she doesn't. Where she is now, in the heat of her high from the affair, those words would probably be just what she want to hear. Would give her justification to leave and conveniently blame me.
