I don't want any man who's had any relationship with her, past or present, on my property. Period.
When my w moved out she specifically asked me not to be there. I thought for sure an OM would be there helping her. That was very painful to think about at the time. But I knew that asking about this or complaining about this would just push my w away. To this day I don't know if she was helped by an OM or not. Draw that line if you need to, but my gut says you should let it go. What she is doing is disrespectful for sure. But she will see you as controlling if you try and stop her.
