cohabiting?
I've seen these symptoms present themselves before. Especially if it's her first time living with a dude. It's kind of a mimi psychotic break from the strain of being unable to control or adapt to her new surroundings... and she just got knocked down a rung on the hierarchical ladder...by a kitten /kitty paw baby swat
typically both parties slip out of initial first few dates "best behavior mode" but the cohabiting freak out is a lot worse and might last a while. It's a good opportunity for you to see just how dark it can get, though it might not seem that way...
you either are a good fit for each other and it will all pan out, or you're headed for splitsville. your control of the situation is limited to your own actions.
might I suggest a swing by your local home depot to check out a set of schlage exterior door knobs with lock matching codes written on them. I highly recommend picking up a complete matching set.
"Heaven has no rage like love to hatred turned / Nor Hell a fury, like a woman scorned."
I've seen some stuff... sometimes a mini break becomes major and it gets a little bit too "here's johnny" / helter skeltr~y for most people
