She is getting frustrated that none of this has resolved her problems or her feelings. We can still have what I see as "nice conversations" and then she flips a switch and is hostile and antagonistic again. This IS the "Roller Coaster Ride from Hell"
I do keep my PMA and composure when she is being negative towards me most of the times. When I cant keep my composure, I just excuse myself and tell her I don't care to talk about things right now.
Regarding moving out; I wont move out unless I have to.
