I would just avoid her, don't move in with her. Is she medicated?
My cousin is Bipolar and she gets all these flight of ideas and it all becomes about her. No one else's thoughts and feelings matter.
Doctors think my husband may be Bipolar 1. He just had his very first manic period and he got hospitalized. Once he got stableized, he is himself again and no more wild mood swings and short temper and lack of impulse and being easily irritated. He was also very delusional. He still is but isn't open about it and he says it still feels all real. But he was getting worse and worse upon hospitalization. My cousin has had several hospitalizations and she isn't even on meds. She is just very energetic and full of spontaneous ideas and it's always about her, my uncle had to put a lock on one of his doors in his home because she wouldn't stop bringing people over and renting out rooms to them. Then she didn't understand why he did it. My family had to revoke her rights to our lake house because she was using it as an air b and b and my brother who is a lawyer said this was a liability thing and dont let her do it.
So it's very different in everyone with it.
