Do you think at this point you'd rather be home when she comes over? After all, it's technically not her house anymore. You could always hang out in the background. Just because you're there, doesn't mean you need to interact with her. OR - you could call her on it - make sure she's coming alone OR you could ask her when OM is coming and see what she says. I dunno - I don't think you really have a basis to trust her right now.
