It's obvious something has changed. It may be a physical change in her, I don't know.
You've got a lot of time and love invested in her so I'd be patience and keep trying to figure out what has happened.
I have a female radix called "The Enforcer" She does a lot of closed mouth strikes on me. It's just her attitude. I've learned to accept it.
Your situation is a little different. Keep working with her and you will probably fine a place in the middle.
Best of luck, keep us informed on your situation.

P.S. Will she take food from your hand?
