First off Matt throw the word coparent out of your vocabulary. It isn't going to happen any time soon. So get rid of the fantasy land idea that you will be working together to raise your daughter. You will have to be the best parent you can be and deal with the crap as it comes. Don't live your life anticipating it, just calmly deal with each situation as it comes along and move on. I am living the same situation, just a bit further along than you.
The not allowing to speak or being impatient when you try to speak is typical. My wife was the same. I could even begin to speak and she would be luck like hurry it up, get it out, I don't really want to hear this and this is why you are wrong. I think it is one of the phases they can go through. You have to just move on again and see if she comes out the other side. You seem to keep getting stuck on the part about she isn't the person she was before. You need to get over this hump and accept right now she isn't that person and may never be again.
