First she still lives with OM, which tells me a lot. Believe none of what they say and only half of what they do ... With that mindset, I feel like she is simply telling me what I want to hear in order to keep me around
L3,
I will let a much more seasoned vet chime in on this to confirm, but I think you've nailed it above. Sooner than later you'll need to set that boundary up that if everything she is telling you is real, OM needs to go away, 100%.
Right now, it sounds like she's trying to make sure her parachute (you) is still packed in case she decides to bail on OM, but she's not quite out of the plane yet.
