It would be helpful to us if you would start your own thread and tell us a little bit about you and your family. Generally around 18-24 months, something occurs that "flips the switch" and they begin to disconnect. Did something occur during that time for your wife?
Your wife is still in crisis ad they have touch and go episodes throughout the crisis. They can be friendly and then turn on a dime. As long as she is not pressured, she will be nice, however, the minute you begin to question her and/or pressure her, she'll distance herself and may even say she wants a divorce. True reconnection takes place very near the end of the crisis and if your wife just moved out recently, I suspect what you are experiencing is a touch and go.
For now, leave her to her journey and keep the focus on you and your daughter. It's a long journey with ups and downs and yes, you'll need plenty of patience and duct tape to keep your mouth shut because she's going to say and do all sorts of things that are out of character for her. As she continues on her journey, she may even become her mirror image, the exact opposite of the woman you know and love.
